摘要： A color image forming apparatus includes a housing and a cartridge adapted to be attached to or detached from the housing in a horizontal direction. The cartridge includes a photoreceptor and a plurality of developing devices vertically piled up. Each developing device has an opening to receive toner and a cover to open or close the opening. When the cartridge is detached from the housing in the horizontal direction and is placed in a laid down position thereof, toner can be supplied into the developing devices through the opening which is at the top portion of the laid-down cartridge.

摘要： Color image forming apparatus includes a belt-shaped image carrier stretched and conveyed around rotating rollers on which image exposure is conducted by a plurality of exposure units; and a plurality of step-formed supporting surfaces below the lower surface disposed of the image carrier. The stepped formation of the exposure unit supporting surfaces avoids interference between optical paths of laser beams for image exposure, and facilitates compactness of the apparatus. The belt-shaped image carrier and the supporting surfaces are provided at a relative angle of 5-30 degrees. The color image forming apparatus is also capable of detecting a specific pattern outputted from the exposure units; calculating the differences of positions of the specific pattern as formed by the different exposure units; and controlling the positioning of the specific pattern as outputted by the exposure units, so as to increase the accuracy of the image forming apparatus.

摘要： In a toner image fixing device, there are provided an endless belt being looped up around a heating roller and a conveyance roller, a pressure roller for pressing a sheet having a toner image onto the heating roller with the endless belt intervening between the pressure roller and the heating roller. A sensor is disposed inside the loop of the belt so as to come in contact with the heating roller, for detecting the temperature of the heating roller. The fixing temperature for the toner image is controlled on the basis of the temperature of the heating roller detected by the sensor. A first nip region is formed on a pressing portion located between the heating roller and the fixing roller. A second nip region is formed between the belt and the fixing roller, continuing from the first nip region but without contacting the heating roller.

摘要： A color copier which can be adopted to a printer operation for a peripheral imaging machine. The color copier forms plural color component toner layers on a photoreceptor layer by layer at each rotation of the photoreceptor. In the mode that the color copier is used as a printer, the copier makes two pages of each of the color component toner layers corresponding to an image at one rotation of a rotatable photoreceptor, when the size of the image is not more than one half the maximum size that can be formed by the copier.
