An image processing apparatus has an input device such as a scanner for inputting an original image, and a mode setting device for setting an editorial processing mode such as trimming, enlargement or size reduction to be executed on the input image. The apparatus further has a processing device for performing, in accordance with the editorial processing mode set by the mode setting device, the editorial processing on the image input by the input device. The apparatus further has a storage control device for storing, in a storage medium such as a disk, the image after the editorial processing performed by the processing device, together with reproduction data which corresponds to the executed editorial processing mode. The reproduction data is used for reproducing the original input image from the image after the editorial processing.

摘要:
An image forming apparatus such as a copier with a detachable process cartridge is provided with a first memory for storing the number of copying operations; a count renewing unit for increasing the count of the first memory and a second memory in the process cartridge, at each copying operation, a comparator for comparing the counts in the first and second memories, and a controller for determining a process condition specific to the process cartridge in case the counts do not mutually coincide. The service life of the process cartridge can be more precisely judged, and the process condition can be more appropriately determined for each process cartridge.

A film type fixing device includes a rotatable endless film; film position detecting device for detecting a position, in a direction perpendicular to a rotational direction, of the film; error detecting device for detecting error of a position of the film when the output of the film position detecting device is out of a predetermined range; and discriminating device for discriminating whether to back up error information or not on the basis of the output of the film position detecting device, when the error detecting device detects the error.
摘要:
An image forming apparatus includes a heater for generating heat upon reception of electric energy; a film movable with a recording material having an unfixed image; and a pressure roller for forming a nip with the heater, with the film interposed therebetween; wherein the pressure roller starts to rotate at the same time as a main power switch of the apparatus is turned on.
摘要:
When the user depresses a soft key SW in an on-state of a door switch DSW in which a door is closed, a transistor Tr1 is turned on, a transistor Tr4 is turned on, a relay RL1 is turned on, and an AC power source is supplied to an image forming apparatus. When a jam occurs, a CPU 2 turns on a transistor Tr5 for a predetermined time and a latching relay RL2 is driven to the holding side. When the door is opened for a jam process, the door switch DSW is opened and the AC power drops. When the door is closed after the jam process, the door switch DSW is closed. In this instance, since the latching relay RL2 is in a holding state, the AC power is again supplied in a manner similar to the case where the soft key SW is depressed. When the jam cancellation is confirmed, the holding of the latching relay RL2 is cancelled and the ordinary operation is started.
