Abstract
A developing apparatus for use in an image forming apparatus employing an electrophotographic copying process, which is capable of providing developed images of a constant image quality over a long period of operation. One of the features is an independent section for accommodating toner particles with different particle diameters within the toner hopper. Seventeen separate embodiments serve to assure an adequate mixture of small to large diameter toner particles to assure image quality.
