ABSTRACT:
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.
