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.

摘要： In the invention, an inclination amount of sensors is reflected in positional deviation correction patterns, and for correcting formation positions of images of various colors, the positional deviation correction patterns are formed on a conveying belt. The positional deviation correction patterns are detected by the sensors. A control unit calculates positional deviation correction amounts based on detection results of the positional deviation correction patterns. Based on the calculated positional deviation correction amounts, the control unit performs calculation for correcting the positional deviation correction patterns, and cancels the inclination amount reflected in the calculation results to obtain final positional deviation correction amounts. Skew correction is performed based on the final positional deviation correction amounts, and thus, the positional deviations are corrected.
