Light source control circuit, image forming apparatus, and method of controlling the light source control circuit |
摘要 |
An optical writing device forms an electrostatic latent image on a photosensitive element by a connected light source controlled by a light source control circuit that includes: a pixel data output unit; a pixel data correcting unit that corrects a skew between main scanning line of electrostatic latent image and photosensitive element and a local deviation of the electrostatic latent image on the main scanning line, and outputs pixel data; a pattern generating unit that outputs pixel data for forming a predetermined pattern in an electrostatic latent image; a first light source control unit for causing a first light source, that needs correction of the local deviation, to emit light; a second light source control unit for causing a second light source, that does not need correction of the local deviation, to emit light; and a switch that switches between a first transmission status and a second transmission status.
