ABSTRACT:
An image forming apparatus includes an exposure area controller for controlling an exposure area per pixel of an exposure device on the basis of image information and a switching device for switching an amount of exposure so as to decrease an exposure intensity of the exposure device during reference toner image formation and increase the exposure area per pixel of the exposure device when compared with those during normal image formation.
