PROBLEM TO BE SOLVED: To detect a rotating state of an image carried and to control a rotating position of the image carrier in response to the detection signal. SOLUTION: This image forming apparatus is constituted so that an interface 706 for state detection is provided with a counter to process encoder output, to be digitally processed and to count the number of encoder pulses, the interface 706 for state detection can take correspondence with a transfer position of an intermediate transfer belt by storing origin information owned by an encoder and an initial position when a power is turned on into a RAM 703, thus, the interface 706 for state detection manages a position of the intermediate transfer belt 704, an interface 712 for driving converts a digital signal of an arithmetic result in a CPU 701 into an analog signal, provides the converted signal to an amplifier for driving motor and controls the rotating position of the image carrier by controlling voltage and current to be applied to a motor 710.
