摘要： An image forming apparatus includes a revolver type developer, and prevents toner stored within the revolver type developer from being adversely influenced by heat from a fixing unit. As one feature, the revolver developing unit is intermittently rotated when the image forming apparatus is in a stand-by state. As a further feature, the revolver developing unit is rotated at a very slow continuous speed when the image forming apparatus is in a stand-by state. As a further feature, the intermittent rotation and the slow continuous rotation of the revolver developing unit can be stopped if the temperature of the fixing unit falls below a predetermined value.

摘要： A full-color image forming apparatus having a photo-conductive belt on which mono-color toner images are respectively formed, an intermediate transfer belt onto which the mono-color toner images are respectively transferred to form a full-color toner image, and a transfer member for transferring the full-color toner image onto a copy sheet. The intermediate transfer belt includes timing marks printed thereon which are detected by a sensor to generate an image forming start signal for each of the first mono-color toner image forming processes. The start signal is generated by a controller only when cleaning of the intermediate transfer belt has completed and the cleaning blade has left therefrom. A timer may be used to delay the starting of the first mono-color image forming process until the transfer belt returns to a normal operating speed after the cleaning blade is removed from the transfer belt.

摘要： A color image forming apparatus capable of superposing toner images of respective colors in accurate register by preventing an exposing position from being displaced in the subscanning direction. The rotation phase of a polygonal mirror is controlled on the basis of the mark detection timing of a mark sensor. Hence, the exposing position in the subscanning direction is prevented from being displaced without regard to irregularities in the circumferential length and feed speed of an intermediate image transfer belt.

摘要： An image processing apparatus eliminates a detection error in a color offset detecting operation due to a periodic fluctuation in a speed of a conveying belt which conveys a transfer sheet on which color component images are transferred and superimpose to form a multi-color image. A plurality of image forming units are arranged along the conveying belt, each of the image forming units transferring a color component image on the transfer sheet and also transferring a register mark on the conveying belt. A register mark detecting sensor located along the conveying belt detects the register mark on the conveying belt. A distance between the register mark detecting sensor and one of the plurality of image forming units adjacent to the register mark detecting sensor is a multiple of an integer of a circumference of the drive roller. A distance between adjacent ones of the plurality of image forming units is a multiple of an integer of the circumference of the drive roller.
