Abstract

An image forming apparatus which forms an image on a recording material, which has: a writing section to write according to the image data; an oscillator to generate a synchronized synchronizing clock signal; a spreading clock generator to spread the band of a synchronized reference clock and generate spreading clock signals; and a plurality of control circuits to control the image forming apparatus and each section of the image forming apparatus including a writing control circuit to control the writing section. More than one control circuits in the control circuits other than the writing control circuit are driven by the spreading clock signals, and the writing control circuit is driven by the synchronizing clock signal.
