Abstract
An image forming apparatus includes: a plurality of optical scanning parts that scan a photoconductor with light of plural colors to form an electrostatic latent image on the photoconductor based on print data; and a controller that, based on a first optical scanning part to which a horizontal synchronization signal is applied of the optical scanning parts, calculates an offset value for light-scan of a second optical scanning part of the optical scanning parts, and controls the optical scanning parts to scan the photoconductor with the light according to the calculated offset value.
Claims19
An image forming apparatus comprising:
- a plurality of optical scanning parts that scan a photoconductor with light of plural colors to form an electrostatic latent image on the photoconductor based on print data;
- and
- a controller that, on the basis of a first optical scanning part to which a horizontal synchronization signal is applied of the optical scanning parts, calculates an offset value for a light-scan of a second optical scanning part of the optical scanning parts, and controls the optical scanning parts to scan the photoconductor with the light according to the calculated offset value.
A signal synchronizing method of an image forming apparatus including a photoconductor on which an electrostatic latent image is formed based on print data, and a plurality of optical scanning parts that scan the photoconductor with light of plural colors, comprising:
- calculating, on the basis of a first optical scanning part to which a horizontal synchronization signal is applied among the plurality of optical scanning parts, an offset value for a light-scan of a second optical scanning part of the plurality of optical scanning parts;
- and
- scanning, the photoconductor with the plurality of optical scanning parts with the light according to the calculated offset value.
A signal synchronizing method of an image forming apparatus including a photoconductor on which an electrostatic latent image is formed based on print data, and a plurality of optical scanning parts that scan the photoconductor with light of plural colors, comprising:
- applying only one horizontal synchronization signal to a first optical scanning part among the plurality of optical scanning parts;
- calculating an offset value for a light-scan of a second optical scanning part among the plurality of optical scanning parts from the horizontal synchronization signal applied to the first optical scanning part;
- and
- scanning the photoconductor with the plurality of optical scanning parts with the light of plural colors according to the calculated offset value.
