Abstract
An image forming apparatus including an image forming unit for forming an image on a recording sheet including a special sheet, and a controller for allowing the image forming unit to carry out an image forming sequence which forms an image on the recording sheet, wherein the controller allows the image forming unit to control a cleaning operation of the image forming unit in response to image formation on the special sheet by the image forming unit.
Claims17
An image forming apparatus comprising:
- an image forming unit for forming an image on a recording sheet including a special sheet;
- and
- a controller for allowing the image forming unit to carry out an image forming sequence which forms an image on the recording sheet,
- wherein the controller allows the image forming unit to control a cleaning operation of the image forming unit in response to image formation on the special sheet by the image forming unit.
An image forming apparatus comprising:
- an image forming unit for forming an image on a recording sheet including a special sheet;
- and
- a controller for sending the recording sheets at predetermined recording sheet distances from one another to the image forming unit,
- wherein the controller sends the recording sheets at longer recording sheet distances than the predetermined recording sheet distances to the image forming unit in response to image formation on the special sheet by the image forming unit.
An image forming apparatus comprising:
- an image forming unit for forming an image on a recording sheet including a special sheet by an image-carrier;
- and
- a controller for controlling timing for allowing the image-carrier to carry images such that the image-carrier carries the images at predetermined image distances from one another,
- wherein the controller controls the timing for allowing the image-carrier to carry the images such that the image-carrier carries the images at longer image distances from one another than the predetermined image distances in response to image formation on the special sheet by the image forming unit.
An image forming apparatus comprising:
- an image-carrier for carrying a developer;
- a transferring device for transferring the developer carried by the image-carrier to a recording sheet;
- and
- a controller which selectively carries out first control for controlling the transfer device such that the developer carried by the image-carrier is transferred to the recording sheet, and second control for controlling the transfer device such that a developer which adheres to the transfer device is transferred to the image-carrier,
- wherein when the developer is transferred to a special sheet, the controller controls the transfer device by the first control and then, controls the transfer device by the second control.
An image forming apparatus comprising:
- an image-carrier for carrying images;
- a transfer device for transferring the images carried by the image-carrier to a recording sheet;
- and
- a controller for controlling a distance between a rear end of the image carried on the image-carrier and a leading end of a next image in accordance with a kind of the recording sheet.
