    Abstract: A printing system receives print jobs having pages that are separated by different levels of ink use to print the pages. The number of pages for different ink use levels are determined as well as the cost estimation to print the different pages. Ink use and cost estimates are provided on a granular level as opposed to overall ink use and costs for printing a print job. Modifications are made to one or more pages to lower ink use for those specific pages as opposed to the print job as a whole. The printing system displays the different ink use levels as well as the cost estimates.

    Abstract: An image forming apparatus includes first, second, and third acquisition processing portions. The first acquisition processing portion acquires the potential value of a charged area, charged by the charging member, on the image-carrying member. The second acquisition processing portion acquires a state value regarding the state of a surface layer of the image-carrying member based on the potential value of the charged area acquired by the first acquisition processing portion and the current value of a charging current flowing through the charging member during formation of the charged area. The third acquisition processing portion acquires the electrical resistance value of the transfer member based on the state value acquired by the second acquisition processing portion, the voltage value of a transfer voltage applied to the transfer member, and the current value of a transfer current flowing through the charged area in response to application of the transfer voltage.

    Abstract: An image forming apparatus includes a developing member, a first detection processing portion, and an acquisition processing portion. The developing member conveys developer to a facing portion between the developing member and the image-carrying member. The first detection processing portion detects a first development current for each of a plurality of specific voltages with different DC voltage values applied to the developing member, the first development current flowing, in response to application of the specific voltages, through the facing portion including the developer and a specific exposed area, formed by the light emitting portion, on the image-carrying member. The acquisition processing portion acquires a potential value of the specific exposed area based on the DC voltage values of the specific voltages and current values of the first development current, detected by the first detection processing portion, corresponding to the respective specific voltages.

    Abstract: An object of the present invention is to reduce loads during a punching process and to reduce punching time. A punching blade is provided with a blade edge portion including multiple peaks and multiple valleys formed alternately in a circumferential direction. A blade edge line of the blade edge portion has first areas corresponding to the valleys, second areas extending from the peaks to the valleys, and third areas connecting the first areas and the second areas. In a side view of the blade edge portion, the first areas form curved lines along first arcs having a center point on a punching axis, the second areas form curved lines along second arcs having center points located in areas between the punching axis and the highest points of the peaks, and the third areas form straight lines along common tangents to the first arcs and the second arcs.

    Abstract: An image information transmission method includes receiving, determining, requesting, causing, and cancelling. In the receiving, an instruction to transmit image information to an image forming apparatus is received from an information communication terminal. In the determining, information relating to a location of an operator of the information communication terminal that is stored in storage is referenced upon execution of the receiving. In the determining, whether or not the operator is in a site where the image forming apparatus is installed. In the requesting, when the operator is not in the site where the image forming apparatus is installed, the information communication terminal requests the operator to determine whether to transmit the image information to the image forming apparatus.

    Abstract: A feeder includes a conveyance path, a conveyance roller that conveys a sheet along the conveyance path, a transmitter that emits a space propagating energy, a receiver that receives a reflected energy obtained by reflection of the space propagating energy, and an actuator mounted pivotably on a pivot shaft and including first and second legs extending in different directions from the pivot shaft. The first leg is disposed to extend to the conveyance path and abut against the sheet being conveyed along the conveyance path. The second leg has a reflective surface crossing a path of the space propagating energy. The actuator is pivoted by abutment of the sheet against the first leg. The reflective surface is formed so that the reflected energy obtained by the reflection of the space propagating energy on the reflective surface enters the receiver regardless of an angle of pivotal movement of the actuator.

    Abstract: A sheet conveying device includes a sheet conveying passage and a switching guide. The switching guide switches the sheet conveying passage between first and second sheet conveying passages. The switching guide includes a plurality of guide ribs and guide members. The plurality of guide ribs are disposed at intervals in the sheet width direction and extend in the sheet conveying direction. The guide members are fitted to specific guide ribs selected from the plurality of guide ribs. The plurality of guide ribs have first and second guide surfaces that guide the sheet. The guide members are formed of a material having higher slidability than the plurality of guide ribs, and have third guide surfaces that are disposed at positions protruding further to an inner side of the sheet conveying passage than the first or second guide surfaces.

    Abstract: In an image forming apparatus, a control device functions as a controller and a user presence/absence determiner. When accepting an instruction to execute a print job through a touch panel, the controller controls operations of a sheet feed device, a conveyance device, and an image forming device to allow a document image represented by image data generated by a document reading device to be formed on a sheet to make a printed matter and allow the printed matter to be discharged to a sheet output tray. When the user presence/absence determiner determines that a user is present, the controller controls, before printing for at least a last sheet in the print job, the operations of the sheet feed device and the conveyance device to allow a sheet to be discharged to the sheet output tray without allowing the image forming device to form the document image on the sheet.

    Abstract: An image forming apparatus includes a photosensitive drum, a charging roller, a development device, a transfer roller, a first electricity eliminator and a controller. The photosensitive drum is provided on a conveyance path along which a sheet is conveyed. The charging roller charges the photosensitive drum. The development device develops an electrostatic latent image formed on the photosensitive drum charged by the charging roller. The transfer roller faces the photosensitive drum across the conveyance path and generates a transfer bias. The first electricity eliminator irradiates the photosensitive drum with light on a downstream side of the development device in a rotational direction of the photosensitive drum and on an upstream side of the transfer roller in the rotational direction. The controller which controls the first electricity eliminator so as to irradiate only a non-sheet passing area of the photosensitive drum with the light.
