摘要:
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 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.

An image forming apparatus includes a fixing unit that performs thermal fixation for a sheet on which a developer has been transferred, and a controller that sets a temperature of the fixing unit at one of a first temperature for fixing a developer expressing a monochrome image on a sheet and a second temperature for fixing developers expressing a color image on a sheet, wherein if a color page is contained in an image forming job, the controller sets the temperature of the fixing unit at the second temperature and starts the image forming job.

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.
