    摘要： An apparatus and method of forming a color image on a recording sheet by transferring respective images onto a single recording sheet conveyed by a conveying belt, where the combination of the respective images form the color image. The respective color images are formed with a plurality of electrophotographic processing sections disposed along the conveying belt such that the respective color images are superimposed on one another to make the color image. The electrophotographic processing sections also form more than two colors, of a same pattern, of image positional deviation detecting marks. The image positional deviation detecting marks include a line in a main scanning direction and another line positioned at an incline with respect to the former line in order on the conveying belt. A detector is included that detects the image positional deviation detecting mark with a single detecting device composed of a light source, a slit, and a light accepting element.

    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.

    摘要： An image forming apparatus includes a plurality of image formation units which print an image of different color on a paper and also form positional deviation detection marks and image density regulation marks, on a conveyer belt or on at least one of a recording medium and an intermediate transfer body that conveys the paper, when such a request is received. When requests for formation of the positional deviation detection marks and the request for the formation of the image density regulation marks is received at the same time or at substantially the same time, the main CPU orchestrates the conveyer belt and the image forming units to form the positional deviation detection marks and the image density regulation marks in continuation.
