Classification: CPC G  H | IPC G  H

Claim 10:
11. The image forming apparatus according to claim 10, wherein
the at least one processor includes a first generation circuit configured to generate a synchronization signal, a second generation circuit configured to generate a synchronization signal, and a selection circuit configured to select as the first synchronization signal either the synchronization signal generated by the first generation circuit or the synchronization signal generated by the second generation circuit,
the first generation circuit includes:
a first holding unit configured to hold a count value of a clock signal, and
a second holding unit configured to hold the magnification in the direction corresponding to the direction of rotation of the first photosensitive drum,
the second generation circuit is configured to generate the synchronization signal based on a common reference synchronization signal, and
the selection circuit selects as the first synchronization signal the synchronization signal designated by the at least one processor from the synchronization signal generated by the first generation circuit and the synchronization signal generated by the second generation circuit.
