Abstract
Abstract An electrophotographic apparatus for producing a color image includes an electrophotographic photosensitive member; an image forming device for forming an electrostatic latent image on the photosensitive member in accordance with color image information; a developing device for developing the latent image with color toner particles into a color toner image; a transfer device for transferring the color toner image onto a transfer material; a controller for controlling an image forming condition; wherein the controller detects a condition, and the controller controls the image forming condition to substantially provide a maximum image formation performance in accordance with the detection. <IMAGE>
