Abstract
An optical scanning device includes a light source, an optical element, a light deflector, a first storage portion, a second storage portion, and a correction processing portion. The first storage portion stores, in advance, first information that indicates relationship between positions on the image carrying member and light amounts of the laser beam irradiated on the image carrying member. The second storage portion stores, in advance, second information that indicates relationship between the control signal input to the light source and a light amount of the laser beam irradiated at a predetermined reference position of the image carrying member in the main scanning direction. The correction processing portion corrects the control signal for controlling the laser beam, based on the first information, the second information and information of irradiation positions on the image carrying member in the main scanning direction at which the laser beam is to be irradiated.
