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.

There is provided an image forming apparatus which is capable of operating in a stable condition and in an efficient manner by omitting automatic adjustment in the case where there is no necessity of carrying out the automatic adjustment when the image forming apparatus returns from a power-saving mode to a normal mode. A CPU shifts the operation mode of the image forming apparatus to a power-saving mode in which power consumption is saved. The CPU detects at least one of a status of the image forming apparatus before the operation mode is shifted to the power-saving mode and a status of the image forming apparatus in the power-saving mode. The CPU determines the contents of a return process executed when the operation mode returns to a normal mode from the power-saving mode, according to the detected status of the image forming apparatus.

The present invention provides an image forming apparatus which, when switching operation from color image forming operation to monochromatic image forming operation, forms a monochromatic image on each of a prescribed number of sheets by stopping a part of the functions of yellow, magenta and cyan image forming sections of the color image forming operation, and thereafter, forms a monochromatic image only with a black-only image forming section, thereby permitting extension of service life of the image forming sections, while improving the productivity.

There is provided an image forming apparatus capable of setting up a tab sheet mode-operating and configuring environment in which an effective tab sheet mode output can be obtained by a simple operation of selecting feeding of tab sheets and a destination of discharge of the tab sheets. A controller is responsive to instruction of feeding of the tab sheets, for providing control to automatically select the cassettes or the multi manual feed tray or the deck that can feed tab sheets that enable a valid image transfer result to be obtained, according to a sheet discharge destination selected by a user for the face-up discharge tray or the face-down discharge tray and a page order designated for the cassettes or the multi manual feed tray or the deck, which is indicated by sheet management information.

摘要:
A color image forming apparatus including image forming portions for respective color components of yellow, magenta, cyan, and black. It can be set whether a discriminating function of discriminating whether an original image is a color image or a monochromatic image is used. If the use of the discriminating function is set, a preparatory operation of forming the image in a full-color recording mode is performed before obtaining a result of the discrimination. When the result of the discrimination is monochrome, the image formation in a monochrome recording mode is executed after a shift from the full-color recording mode to the monochrome recording mode. If configured to perform the preparatory operation of forming the image in the monochrome recording mode before obtaining the result of the discrimination, when the result of the discrimination is color, the image formation in the full-color recording mode is executed after a shift from the monochrome recording mode to the full-color recording mode.
摘要:
There is provided an image forming apparatus which is capable of reducing a period of time required for obtaining an image output, in the case of changing the image forming operation from a monochromatic image formation to a color image formation during execution of the image forming operation. A plurality of image forming units form images and overlap images the formed images onto a transfer material. A preparation for image formation is started in a first mode in which image formation is carried out by the plurality of image forming units while image formation is being carried out in a second mode in which image formation is carried out by at least one of the image forming units. The image formation is carried out in the first mode after the image formation in the second mode is completed.
