PROBLEM TO BE SOLVED: To shorten a warming up time by providing a parking position deciding means, a photoreceptor speed control means for judging whether to adjust the rotational speed of a photoreceptor or not from the result of the decision with the means, so as to control the rotational speed of the photoreceptor, etc. SOLUTION: A belt marker arranged on a photoreceptive belt is detected by a belt marker detecting sensor and a belt marker detecting circuit 110. Further, a photoreceptive belt parking position detecting means 111 detects the parking position of the photoreceptive belt, based on a belt marker detecting signal BMS of the output of the belt marker detecting circuit 110. The detected photoreceptive belt parking position and a photoreceptive belt parking position stored in a photoreceptive belt parking position storing means 113 are compared by a photoreceptive belt parking position comparing means 112 and a command that the speed of a photoreceptive belt motor is adjusted or not is issued to a belt motor speed control means 101. |
