Abstract
An image forming unit includes a first receptor, a light source, a photosensitive member, a rotational polygon mirror, a light receiving unit, an identifier configured to identify a reflection face, and a generator. An information processing apparatus includes a second receptor, a first detector, a second detector, a determiner, a corrector configured to correct image data, and an output unit configured to output corrected image data to the image forming unit. When the first change is newly detected in a predetermined period, the determiner determines, based on a time period from the second timing at which the first change is newly detected to a timing at which the second change is detected and a time period from the first timing to a timing at which the second change is lastly detected before the second timing, whether the first change is a change corresponding to the identified reflection face.
