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.

Image forming apparatus for forming color images and monochrome images

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.

Image forming apparatus and control method therefor

In an image forming apparatus for forming an image in accordance with control codes stored in a plurality of memory media, when the control codes stored in the plurality of memory media to control the image forming apparatus is rewritten, rewrite execution codes adapted to execute rewrite of the control codes are transferred to predetermined one of the plurality of memory media from an external apparatus, and rewrite of the control codes is performed in accordance with the transferred rewrite execution codes.

Image forming apparatus having control codes and rewrite control method for the same

Image forming apparatus

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.

Image forming apparatus with cleaning operation for special sheets

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 cassettesand multi manual feed trayetc. 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 trayand face-down discharge tray, 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.

Image forming apparatus and control method for the same

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.

Image forming apparatus, control method and program for the image forming apparatus, and storage medium

An image formation apparatus which has a memory for storing plural read images is provided. In the apparatus, setting of a second copy job and image reading are possible even if a first copy job is being executed. Further, even if feeder jam or printer jam occurs in the first copy job when the second copy job is being set, such the jam is displayed at appropriate timing, so that operability of the apparatus can be significantly improved.

Image formation apparatus having image memory

An image forming apparatus includes an image forming unit for forming images on sheets in the copy mode, the facsimile mode, and the printer mode a plurality of storage units for storing the sheets on which images are formed by the image forming unit, a setting unit for setting storage units which are to store sheets on which images are formed in the respective modes, a detection unit for detecting empty states of the storage units, and a control unit for storing sheets on which images are formed in the facsimile or printer mode in the storage units that are set by the setting unit, and storing sheets on which images are formed in the copy mode in storage units whose empty states are detected by the detection unit independently of the setting state of the setting unit.

Image forming apparatus for forming image in copy mode and mode other than copy mode

An image forming apparatus for inputting an original image and forming an image on a recording medium, includes an image direction detection unit for detecting the image direction of an original image, and a control unit for controlling image forming device to perform predetermined image forming processing in accordance with the detection result of the image direction detection unit. The image direction detection unit outputs a degree of determination as the detection result of the image direction, and a level for determining whether or not the predetermined image processing is done is set for the degree of determination.

Image forming method and apparatus

An image forming apparatus includes an image forming device for forming an image on a sheet, a tray for stacking a sheet on which the image is formed by the image forming device, a shifting device for shifting the sheet for each copy to stack the sheet on the tray, and a control device for controlling the shift operation of the shifting device at the time of the shift mode, wherein the control device controls the shifting device in such a manner that the shifting device does not shift the sheet when the number of the sheets per one copy is one while the shifting device shifts the sheets when the number of the sheets per one copy is two or more.
