摘要： An image forming apparatus includes a control portion, a stop processing portion, a resumption processing portion, and a notification processing portion. The control portion, to which power supply is stopped when an operation mode of the image forming apparatus is a power-saving mode, measures an elapsed time until when printed matter processed according to the print job is collected. The stop processing portion, when the operation mode shifts to the power-saving mode, stops measurement of the elapsed time before power supply to the control portion is stopped. The resumption processing portion, if the printed matter exists in the sheet discharge portion when the operation mode shifts to a normal mode, resumes measurement of the elapsed time by the control portion. The notification processing portion, when the time measured by the control portion reaches a predetermined first reference time, notifies that the printed matter has not been collected.

摘要： An image forming apparatus includes: a transfer unit, a reflectance sensor, a time-series data acquiring unit, and a transfer-unit rotation-time calculating unit. The time-series data acquiring unit is configured to acquire time-series data with respect to the image carrier background-portion reflectance, measured by the reflectance sensor, as reference data over a time period twice longer than a time period that by design the image carrier requires for one cycle, and as advance/delay data over a time period twice longer than a time period longer or shorter in multiples of a predetermined time interval than the by-design time period. The transfer-unit rotation-time calculating unit is configured to calculate a one-cycle-time calculation value that is the time actually required for one cycle of the image carrier, based on the reference data and the advance/delay data acquired by the time-series data acquiring unit.

摘要： An image forming apparatus includes an image forming portion, a curling correction portion, a curling direction determination portion, and a rotation control portion. The image forming portion forms an image on a recording medium. The curling direction determination portion determine a direction of curling in a recording medium in which images forms on both surfaces thereof, based on an image density of each of both surfaces of the recording medium in which the images forms on both surfaces thereof. The rotation control portion is configured to rotate the curling correction portion such that the curling correction portion is set in an orientation for correcting the curling that has occurred in the recording medium, in a direction opposite to the direction of the curling determined by the curling direction determination portion.

摘要： An image forming apparatus according to one aspect of the present disclosure includes an image forming portion, a curling correction portion, and a speed control portion. The image forming portion forms an image on a recording medium. The curling correction portion has one pair of rollers composed of members that respectively have different elasticities and are pressed against each other, and corrects curling that has occurred in the recording medium after image formation performed thereon by the image forming portion, by conveying the recording medium sandwiched with the roller pair. The speed control portion changes a conveyance speed of the recording medium by the roller pair based on a density value of an image formed on the recording medium.

摘要： An image forming system includes an image forming apparatus and an insertion device. The image forming apparatus includes an image forming device, a transport device, and a control device. The control device acts as a controller and an executer. The controller causes the image forming device to execute a printing job, and causes the insertion device to insert the interleaving paper in a printed material at an insertion start timing designated by the printing job. The executer executes calibration at an execution start timing set in advance, and sets a time point that a predetermined time has elapsed after a previous calibration to the execution start timing in advance. The executer starts to execute the calibration at the insertion start timing, when a predetermined condition is satisfied.

摘要： An image forming apparatus connected to a charging device includes an image forming unit, a fixing unit, a charge processor, a controller, and a printed sheet counter. The charge processor charges a fee for printing. The controller selects an energy saving mode, upon deciding that a balance of a deposited amount in the charging device is less than a threshold amount. The printed sheet counter counts the number of sheets of the recording medium printed by the image forming unit in one single printing job. The controller selects the energy saving mode for the next printing job, upon deciding that the number of sheets printed in one single printing job is less than a predetermined threshold number of sheets, when the deposit balance is remaining in the charging device.
