摘要： An optical writing control device includes: a light emission control unit which controls light emission of multiple light sources for respective different colors and exposes multiple image carriers; and a correction amount calculating unit which calculates a correction amount for each of the different colors on the basis of a difference between a central value of a distribution range of positional deviation amounts in a sub-scanning direction for the respective different colors and the positional deviation amount for a corresponding color. The light emission control unit delays light emitting timing of a light source, which is to be delayed, by delaying reading timing of pixel information stored in a storage medium, and delays timing at which the pixel information about colors other than a color, light emitting timing of a light source for which is to be advanced, starts to be obtained from an image forming apparatus main body.

摘要： An optical writing device is configured to form electrostatic latent images on a plurality of photosensitive elements by a plurality of light sources. The optical writing device includes: an image-data acquiring section that acquires image data; and a light-source control section that performs light-emission control on the light source based on pixel data generated from acquired image data, and also performs a neutralization process on the photosensitive element by controlling the light source to expose the photosensitive element to light. In the neutralization process, the light-source control section divides a period during which light-on/off control can be performed on the light source, into sub-periods based on pixel data input to the light-source control section, and causes the light sources to be lit in any one of the sub-periods so as to always place at least one of the plurality of light sources in a light-off state.
