Abstract
A color image forming apparatus is an apparatus in which toner images are successively transferred from a plurality of image bearing members to a transfer material, and which is for ensuring the toner images transferred to the transfer material to be transferred to a predetermined position. In the apparatus, patterns depicted on the surface of the image bearing members are read along with the movement of the image bearing members, and on the basis of the read result, control is effected so that the peripheral speed of the image bearing members is constant.
