ABSTRACT:
An image forming apparatus includes a plurality of image bearing members that bear a latent image each and a detector corresponding to each image bearing member. The detectors optically detect density of toner images present on corresponding one of the image bearing members. At least two of the detectors are shifted in the direction of the axis of rotation of the corresponding image bearing member as compared to other detectors.
