摘要： There is provided a sheet processing apparatus that is capable of preventing sheets conveyed to the sheet processing apparatus from being skewed, wrinkled, damaged, or jammed, and prevent sheets stored in the sheet processing apparatus from being misaligned. The sheet processing apparatus receives a sheet discharged from an image forming apparatus comprising fixing rollers that hold and convey a sheet on which is formed an image at a first conveying speed and with a first conveying force, discharge rollers disposed downstream of the fixing rollers in a sheet conveying direction, for conveying the sheet at a second conveying speed higher than the first conveying speed and with a second conveying force smaller than the first conveying force, and a controller that determines whether a trailing end of the sheet is released from the fixing rollers. In the sheet processing apparatus, sheet discharge rollers convey the received sheet, and a controller sets the conveying speed of the sheet discharge rollers to the first conveying speed while the sheet is being conveyed by all of the fixing rollers, the discharge rollers, and the sheet discharge rollers, and sets the conveying speed of the sheet discharge rollers to the second conveying speed after the controller determines that the trailing end of the sheet is released from the fixing rollers.

摘要： An image forming apparatus that can prevent image deletion in carrying out image formation upon turning-on of power supply after main power supply is turned off before the image forming apparatus goes into a sleep state. A movable member is moved between a shielding position at which it shields a photosensitive drum from a charger and a retracting position at which the photosensitive drum and the charger are opened to each other. When power supply is turned on, a time period for which the photosensitive drum is rotated by a driving unit is controlled according to the position of the movable member detected by a movable member sensor.

摘要： A sheet stacking apparatus includes an alignment member to align a sheet stacked on a stacking tray in a width direction perpendicular to a direction in which the sheet is discharged. When stacking a plurality of sheets on the stacking tray, the sheet stacking apparatus lowers the stacking tray, so that a predetermined distance is maintained between the top surface sheet and a sheet discharge port. If the stacking tray is lowered to a predetermined position while the alignment unit is executing an alignment operation at a first position, the sheet stacking apparatus lowers the alignment member to a second position lower than the first position and causes the alignment member to execute the alignment operation at the second position.

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： Timing information for use to determine the timing to discharge a sheet from an image forming apparatus is transmitted. The timing information is relayed, by being edited repeatedly, from a first sheet processing apparatus connected directly with the image forming apparatus to a second sheet processing apparatus which actually processes the sheet. The timing information is edited on each sheet processing apparatus by considering, for example, transit time of the sheet, processing time of the sheet, preparation time for the sheet to get ready to be processed, and the like. The second sheet processing apparatus transmits the timing information to the image forming apparatus. The image forming apparatus determines the discharge timing of the sheet based on the received timing information and discharges the sheet with the determined discharge timing.
