Abstract
An image forming apparatus, including: a temperature detecting element provided on an opposite side of a first and a second light sources with respect to a deflection unit in an optical box and provided between a first lens and a second lens, which a first and a second light beams emitted from the first and second light sources and deflected by a rotary polygon mirror enter first, respectively, the temperature detecting element being configured to detect an internal temperature of the optical box; and a control unit configured to control lighting-up timings based on image data of the first and second light sources based on a detection result of the temperature detecting element so that misregistration between a first toner image and a second toner image transferred from the first and second photosensitive members onto the sheet is suppressed.
