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 simple selecting and designating operations, A designating device designates a type of sequence of tabs of each of tab sheet bundles set in the sheet feed devices such as cassettes 21a-21d and multi manual feed tray 27 etc. A determining device is responsive to a user's instruction for feeding tab sheets and selection of a combination of one of the sheet feed devices and one of the sheet discharge devices such as face-up discharge tray 2 and face-down discharge tray 3, for determining whether a combination of the selected sheet feed device, the selected sheet discharge device, and the type of sequence of tabs of the tab sheet bundle set in the selected sheet feed device is valid or not.

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.
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.
