ABSTRACT:
An electrophotographic color image forming apparatus, having: a plurality of photosensitive media; a plurality of transfer rollers respectively facing the plurality of photosensitive media; and a belt disposed between the photosensitive media and the transfer rollers and circulating while forming a plurality of transfer nips. When a length of the belt between two neighboring transfer nips is B and a distance between a pair of neighboring photosensitive media is C, B is larger than C, and when respective virtual lines connecting centers of the pair of photosensitive media and centers of corresponding transfer rollers are TP lines and a virtual line connecting the centers of the pair of neighboring photosensitive media is PP line, a pair of neighboring TP lines do not cross the PP line at right angles, and are slanted toward the same side to cross the PP line.
