IMAGE FORMING APPARATUS

摘要

An image forming apparatus includes a light source, a reflector, a photosensitive member, a light receiver, and an integrated circuit chip. The integrated circuit chip outputs, to the light source, a lighting signal for controlling lighting of the light source. The integrated circuit chip includes a synchronizing signal output circuit, a receiver, a first OR circuit, and a first wiring line. The synchronizing signal output circuit is configured to output a synchronizing signal for lighting the light source. The receiver is configured to receive a first image data signal outputted from an external circuit, the first image data signal being for lighting the light source. The first OR circuit is configured to output a first lighting signal that is a logical sum of the synchronizing signal and the first image data signal. The first wiring line connects the synchronizing signal output circuit with the first OR circuit.

1. An image forming apparatus comprising:
a light source; a reflector configured to reflect a light beam emitted from the light source; a photosensitive member configured to be irradiated by the light beam reflected by the reflector; a light receiver configured to receive the light beam reflected by the reflector; and an integrated circuit chip configured to output, to the light source, a lighting signal for controlling lighting of the light source, the integrated circuit chip comprising: a synchronizing signal output circuit configured to output a synchronizing signal for lighting the light source; a receiver configured to receive a first image data signal outputted from an external circuit, the first image data signal being a signal for lighting the light source; a first OR circuit configured to output a first lighting signal that is a logical sum of the synchronizing signal and the first image data signal; and a first wiring line connecting the synchronizing signal output circuit with the first OR circuit.
