摘要:
An image forming apparatus which enables easy management of proofs in a printing process. An image forming apparatus 299 is provided with a reader unit 50, a transfer charger 220, color sensors 274-1 to 274-4, a printer controlling unit 21. The reader unit 50 inputs image data for forming an image on a sheet having an RFID tag 701. The transfer charger 220 generates a transfer image for forming the image on the sheet based on the inputted image data. The color sensors 274-1 to 274-4 measure image formation conditions of the transfer image. The printer controlling unit 21 writes the measured image formation conditions into the RFID tag 701.

A belt feeding apparatus includes an endless belt and a supporting member for rotatably supporting the belt. The belt feeding apparatus further includes a setting member for setting, when the belt is deviated from a widthwisely normal zone, an inclination angle of the supporting member to a return angle to return the belt toward the normal zone, The setting member also sets, when a predetermined time elapses from the belt returning to the normal zone, the inclination angle of the supporting member to a balance angle to keep the belt in the zone.

摘要:
An image forming apparatus which makes it possible to resolve correction error of potential unevenness caused by insufficient mounting accuracy of an image carrier, in a relatively short time period without performing a conventional operation for removing the image carrier. The image forming apparatus includes a photosensitive drum, an exposure unit, an electrical potential sensor, a shading data ROM, and a CPU. Electrical potential data items associated with respective positions on the surface of the photosensitive drum are stored in the shading data ROM. The CPU corrects an exposure amount onto the photosensitive drum by the exposure unit, based on the electrical potential data read from the ROM, and based on the result of correction, adjusts timing for reading out the data.
摘要:
An image forming apparatus that previously rotates a polygonal mirror drive motor before starting a job and forms a latent image by using an optical scanning unit including the polygonal mirror drive motor is provided. The image forming apparatus includes a control unit configured to perform control such that, in the determination of the presence or absence of each of color toners before a previous rotation is started, if it is determined that any one of the color toners is absent, only the polygonal mirror drive motor corresponding to a black toner is previously rotated.
