Abstract
An image forming apparatus and a method of forming an image. A timing generating circuit is constructed without employing an exclusively used IC. A CCD can be easily replaced without performing any new designing. A timing signal is suitably delayed corresponding to a delay time between an input image signal and an output image signal per each of respective processing circuits sequentially connected. The apparatus enables high-speed image processing. The apparatus includes an optoelectric conversion element, a signal processing section, and a timing generating section. The timing generating section includes a first pattern signal generating section which generates a previously established pattern signal, a second pattern signal generating section which repeatedly generates the previously established pattern signal and stops the generation of the pattern signal only during a specified time period of one scanning, and a third pattern signal generating section for putting the previously established pattern signal in an active state only during the specified time period from the generation of a trigger signal in one main scanning.
