Abstract
An image forming apparatus can form a correction image for correcting a positional deviation and includes an image forming unit, an image carrying member, a light detection unit, an ambient condition detection unit, and a control unit. The image carrying member receives the correction image, which is formed by the image forming unit. The light detection unit illuminates the correction image on the image carrying member and detects light reflected thereby. The ambient condition detection unit detects, as an ambient condition, at least one of temperature and humidity in an operating condition of the image forming apparatus. The control unit effects position correction control at a time of image formation of the image forming unit on the basis of a detection result of the light detection unit and an ambient condition detected by the ambient condition detection unit.
