Abstract

PURPOSE:To always form an image in the defined position of a sheet of recording paper by measuring the time from a feeding command to the time of detecting the start of feeding of a register roller and correcting the timing of the feeding command based on the result of the measured time. CONSTITUTION:Since there is a slight lag from the time of commanding the engagement of a register clutch 64 till when a register roller 22 actually starts to operate, an operation controlling part 50 measures the time from the engaging command to the detecting time of the start of feeding detected by a rotary encoder 41 installed on the register roller 22, by means of a housed timer. And, the timing of outputting an engaging command signal to the register clutch 64 is delayed by the amount of difference between the measured time and a theoretical time. Thereby, a reference time from when an exposure starting switch 44 is turned on till when the engaging signal of the register clutch 64 is issued, i.e., the time at which a sheet of recording paper arrives at a sensitive body drum 11 can be made accurate. Thereby, an image can always be formed in the defined position of a sheet of recording paper.
