ABSTRACT:
A device and method for controlling timing for starting image formation, and image forming apparatus using such device and method are described. A detector outputs a synchronization detection signal when a light beam enters the detector. The timing for starting image formation is determined based on timing when a counter value, which is counted from timing when the synchronization detection signal is detected, reaches a reference counter value. The reference counter value may be determined according to an operation mode.
