Abstract

A color electrophotographic printing machine uses three or four developer housings. When the printing machine uses a cylindrical photoconductive drum, each developer housing is arranged in a generally radial pattern relative to the drum. An advantage in this arrangement is that as the distance from the drum center increases, there is more space in the circumferential direction for larger components. However, each housing is at a different angle with respect to gravity so that the developer material flow patterns are not identical. This prevents the developer housings from being identical to one another, and thereby increases manufacturing costs and the number of replacements parts required for maintenance. In order to overcome this problem, the developer housing may be arran ed parallel to one another
