Color image forming apparatus
 A color image forming apparatus is capable of reducing color deviation of an image due to the influence of a variation in load of an intermediate transfer member and of carrying out high speed printing. A control unit for controlling an image forming process on the basis of the size of a recording medium sets, where a recording medium of a size smaller than the longest image length capable of forming a color image is subject to continuous image formation, a first mode for continuously carrying out a development process for forming a latent image and a toner image, and a second mode of incorporating a stop process for stopping the development process in the midst of the development process. This enables reduction of color deviation of an image caused by the influence of a variation in load of an intermediate transfer member and high speed printing also.
