Abstract
A color printer includes an electrophotographic process unit for selectively exposing the photosensitive image carriers to form identical latent images thereon, developing the latent images as toner images by supplying toners of different colors, and transferring the toner images onto paper, and a control circuit for controlling amounts of exposure of the latent images to be formed by the electrophotographic process unit. Particularly, the control circuit includes a toner-save key for selecting a toner-save mode, and processing circuit for lowering the exposure amounts of the latent images in the toner-save mode, while changing a rate of the exposure amounts to compensate for a difference between development properties of the toners.
