Patent Primary Examiner
In an image forming apparatus, a CPU can perform in a normal mode and a low mode in which a photoconductive drum rotates at a rate m/n times the rotational rate in the normal mode, and lower than the rotational rate in the normal mode. In the low mode, the CPU causes a synchronizing signal generation portion to generate a line synchronizing signal at a cycle 1/m times the cycle of the line synchronizing signal generated in the normal mode, and causes a chip data conversion portion to transmit, to an exposure head, the same image data signal m times and transmit, to the exposure head, an image data signal that brings a light-emitting portion into no light emission n-m times, in synchronization with n number of line synchronizing signals.
