ABSTRACT:
A dry process developing apparatus of a type in which, by supplying toner contained in a toner replenishing tank with respect to magnetic carrier magnetically attracted onto an outer peripheral surface of a developing sleeve, a magnetic developing material composed of the magnetic carrier and toner is prepared on the outer peripheral surface of the developing sleeve for developing an electrostatic latent image supported on the surface of an electrostatic latent image support member by the use of this developing material. The developing apparatus includes a space chamber defined between a bristle height restricting member and a front restricting member so as to open towards the outer peripheral surface of the developing sleeve, and preliminarily loaded with the magnetic carrier, and a toner supplying section for supplying the toner with respect to the outer peripheral surface of the developing sleeve at the upstream side of the front restricting member.
