A copy paper supply timing control system includes a slit plate secured to a shaft of a photo-sensitive drum for developing a pulse signal of a period (t') in response to the rotation of the photo-sensitive drum. A copy paper supply system is enabled when a predetermined time has passed after an optical system initiates its movement. The predetermined time is determined by a number (N) of the pulse signals and a time period (T) from the development of the N-th pulse signal. That is, the actual copy paper supply is conducted when (Nxt'+T) have passed after the optical system initiated its movement. The copy paper supply timing control system includes a compensation system for modifying the pulse number (N) and the time period (T) in response to a detected period (t) between the initiation of the optical system movement and the development of the first pulse signal.
