Abstract:
1. An image forming apparatus comprising: an image forming unit for forming a correction image for correcting a positional deviation; an image carrying member for receiving the correction image formed by said image forming unit; a light detection unit for illuminating the correction image on said image carrying member and detecting light reflected thereby; an ambient condition detection unit for detecting, as an ambient condition, at least one of a temperature and a humidity in said image forming apparatus; a correction unit for correcting, on the basis of the ambient condition detected by said ambient condition detection unit, such an error in a detection result of said light detection unit as is attributable to an increase of image density caused at an end portion of the correction image; and a control unit for controlling, on the basis of a correction result provided by said correction unit, a position correction when said image forming unit forms an image.
