摘要： An optical-writing control device calculates correction values for use in correcting a transfer position at which developing-agent images are to be transferred onto a sheet, and overlaying positions at which the developing-agent images are to be overlaid, based on a detection signal output from a sensor upon detection of a correction pattern for use in correcting the transfer position and a correction pattern for use in correcting the overlaying positions. A timing of detecting the pattern for use in correcting the overlaying positions is determined based on a correction value calculated based on the detection signal output upon detection of the pattern for use in correcting the transfer position. The pattern for use in correcting the transfer position is caused to have a width, in the main-scanning direction, that is wider than the width in the main-scanning direction of the pattern for use in correcting the overlaying positions.

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.

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.
