Disclosed is a toner for electrophotography containing at least a binder resin. This toner for electrophotography is characterized in that (a) the tetrahydrofuran (THF) soluble content in the toner has a first peak in the molecular weight region of not less than 2,000 but less than 5,000 and a second peak in the molecular weight region of not less than 100,000 but less than 200,000 in the chromatogram obtained by gel permeation chromatography (GPC); (b) the binder resin contains at least a carboxyl group-containing vinyl resin (C) and a glycidyl group-containing vinyl resin (E); and (c) the mass ratio of the styrene monomer to the acrylic monomer in the binder resin, namely (S/A), is not less than 4.6 but less than 8.5.
摘要:
There are provided an image forming apparatus which is capable of efficiently performing necessary actions to thereby reduce downtime. At least one job can be registered. Image formation is performed according to the at least one registered job. Action objects are detected on which actions necessary for the image forming apparatus should be taken.

The quantity of light of an optical sensor including a light emission portion and a light reception portion is adjusted through calculation before sheet detection is performed. In order to perform the light quantity adjustment, a voltage to be applied to the light emission portion of the optical sensor is obtained by performing calculation based on a relation between a voltage applied to the light emission portion before the adjustment and an output from the light reception portion before the adjustment. Then, it is judged whether the obtained voltage exists within a predetermined range and, if a positive result is obtained, the light quantity adjustment is ended. Further, a signal requesting the cleaning of the optical sensor is outputted in accordance with a value of the obtained voltage.

An optical disk device for correctly positioning on a turntable, an optical disk composed of two optical disks glued together, regardless of how poorly they are attached together. The device includes the turntable, on which the optical disk is placed, a disk holding part onto which a mounting hole of the optical disk is fitted, and a clamping member, which is provided on part of the circumferential surface in the disk holding part, is free to move in the radial direction of the disk holding part, and is impelled radially outward. The clamping member is formed in a mountain shape by two sloping faces and a sloping faces meet. The tip is beveled to a shape such that the tip makes a surface contact with the optical disk when the optical disk is mounted on the turntable.

A sheet perforation device for use in an image forming apparatus eliminates inconveniences such as imperfect punching due to too small a sheet size and completion of image formation without notifying the user that the punching could not be performed despite the user's instruction for punching. Punching setup is made and a starting instruction is given through an operating section. Based on the relationship between a selected sheet size and the spacing of holes to be formed by a punching unit, a determination is made as to whether the punching can be correctly performed, and, if it has been determined that the correct punching will fail, a warning message is displayed on the operating section. If the user gives a starting instruction again after recognizing the warning message, image forming operation is started while the punching setup is automatically canceled.
摘要:
An anti-rattle guide assembly and method for supporting an armrest or other structure which is slidable between extended and retracted positions. The method of preventing rattling of a sliding mechanism include the steps of disposing a moveable rail member on a frame, placing the sliding mechanism in contact with the moveable rail member, and applying a force to the moveable rail member to bias the moveable rail member toward the sliding mechanism so as to maintain contact between the moveable rail member and the sliding mechanism. The guide assembly may be disposed between two such moveable guide rails or between a moveable guide rail and a fixed guide rail.

A method for controlling whether or not to display the status monitor of a device. When a certain application program outputs a printing command and the status monitor of the printer is set to be displayed, data indicative of the application program is first obtained and compared with a list of problem application programs. If the name is not in the list, then the printing status monitor is displayed. However, if the name is found in the list, the status monitor is not displayed. This method increases efficiency of work for the user and prevents such problems as the computer hanging up or the programs being forcibly closed.

An image recording apparatus having an exposure unit, a pressure developing unit and a thermal fixing unit. The apparatus employs a separate type image recording mediums including a microcapsule sheet and a separate developer sheet. The thermal fixing unit applies heat to the developer sheet carrying an output image thereon. A heat application means of the thermal fixing unit is positioned spaced away from the imaging surface of the developer sheet for avoding direct contact therewith.
