<p>PROBLEM TO BE SOLVED: To provide an inexpensive, highly durable and high-speed full color electrophotographic device capable of forming stable images in repetitive use. SOLUTION: In this full color electrophotographic device, the amount of fluidizing agent in developer used in a developing means mounted on an image forming element for forming a black toner image is made smaller than the amount of fluidizing agent in developer used in a developing means mounted on an image forming element for colors other than black, or the amount of wax added to toner used in the developing means mounted on the image forming element for forming the black toner image is made larger than the amount of way added to toner used in the developing means mounted on the image forming element for the colors other than black.</p> |
