An image fixing apparatus includes a heater which is stationary during an image fixing operation, a linear heat generating layer and a film movable in sliding contact with the heater in which a toner image on a recording material is heated by heat from the heater through the film. The heater produces amounts of heat which are different in a direction transverse to a direction of movement of the recording material by varying the resistance distribution of the linear heat generating layer.

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.

Even if a user sets an erroneous setting to a sheet, in order to provide an image formation system which can recycle sheets and improve operability without executing incorrect processing to the sheet, a reference value, which is referred in confirming an abnormal state of the sheet to be conveyed, before a generation of sheet size information is made to differ from the reference value after the generation of the sheet size information on the basis of a sheet detected result. In accordance with the sheet size information to be confirmed and the sheet size information acquired according to an instruction from an operator, processing corresponding to the instruction from the operator to the sheet is invalidated. An image formation operation is interrupted in accordance with the sheet size information to be confirmed and the sheet size information acquired according to the instruction from the operator.

An image processing apparatus includes a first processor for outputting first image data and a second processor for outputting second image data different from the first image data. The apparatus also includes a first detector for detecting a processing stage of the first processor and a second detector for detecting a processing condition of the second processing means. The apparatus also includes means for judging whether operations, to interrupt the processing by the first processor and to execute the processing by the second processor, are permitted or inhibited on the basis of a first detection result of the first detector and a second detection result of the second detector.
摘要:
An image formation apparatus comprises an image formation device for forming an image on a recording material according to image information light obtained from light emitted from a light source. A detector detects the light intensity emitted from the light source. A single cooling fan is provided for cooling both the light source and the image formation device. The drive force of the cooling fan is set at either a first value or a second value. The driving force is set at the first value during a time period from a start of energization of the light source until the light intensity detected by the detector is at least the predetermined value. The driving force is set at the second value after the detected light intensity is at least the predetermined value. The first value of the driving force is less than that of the second value.

摘要:
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.
