Abstract
A photoelectronic image forming apparatus reproduces an image on the basis of an electrostatic latent image produced on a photo-sensitive body by using a developer containing a toner and a carrier, and comprises a plurality of toner density measuring units for respectively producing outputs each indicative of a toner density of the developer and a toner density determining unit responsive to the outputs for determining an actual toner density so as to precisely control the tone of the image.
