摘要： The present invention provides an electrophotographic image forming apparatus capable of forming a high quality image by eliminating an expansion/contraction, displacement in color or nonuniformity of color of the image formed on a transfer member. An image carrier gear for driving an image carrier is driven by a driving means gear at an image carrier driving position and transmits driving force to conveying force transmitting gear at a transfer driving position. The conveying force transmitting gear transmits conveying force to the transfer member. A time during which the image carrier moves from a latent image forming position to a transferring position is made substantially equal to a time during which the image carrier gear moves from an image carrier driving position to a transfer driving position.
