Abstract

It has been found that development of an electrostatic latent image in an electrophotographic printing machine can be improved by controlling the spacing between the photoconductive surface and the developer roller. With the increased usage of flexible photoconductive belts and magnetic brush developer rollers, it is feasible to control the spacing therebetween. When the photoconductive belt is maintained at the proper tensioning, it is practical to permit the developer material to space the photoconductive belt from the developer roller. As shown in the drawing, development system 38 includes a housing 68 defining a chamber for storing a supply of insulating developer material therein. A pair of augers 70 mix developer material in the chamber of housing 60 and advance the developer material to developer roller 40. Developer roller 40 advances the insulating developer material into contact with the electrostatic latent image recorded on
