Abstract
An image forming apparatus is provided for controlling current(s) supplied to a semiconductor laser. In one or more embodiments, an image forming apparatus corrects a value of the driving current and a value of at least one correction current (e.g., first and/or second correction current(s)) supplied in synchronization with the supply start of the driving current based on a reception result of a light receiving unit. In one or more embodiments, an image forming apparatus includes a correction current supply unit including a first correction current generation unit for generating a first correction current that attenuates over time and a second correction current generation unit for generating a second correction current that attenuates over time and of which an attenuation speed is lower than that of the first correction current, and configured to supply the first correction current and the second correction current to the semiconductor laser.
