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.
