摘要： The image forming apparatus includes a photosensitive drum, an image forming unit, an intermediate transfer belt, a circuit of a drive motor which outputs information on a moving distance, a registration roller, a CPU which calculates the predetermined timing on the basis of the information on the moving distance output by the circuit of the drive motor at the time when a rotation speed of the intermediate transfer belt is switched from a first process speed to a second process speed, and a memory storing the information on the predetermined timing calculated by the CPU, wherein the CPU controls the registration roller so as to start the conveyance of the recording material at the predetermined timing stored in the memory. Consequently, a positional relation between a leading end of the recording material and a leading end of the image formed on the recording material can be set as a desired positional relation.
