Abstract

See full text

An improved toner module for use in an electrophotographic print engine. A decorator or developer roller with a rotatable core provides an apparatus for, and an improved method of, replacing developer. The decorator roller has a core that is partially magnetic and partially nonmagnetic. By rotating the decorator core to adjust the position of the non-magnetic portion of the decorator core, developer can be both removed and added without the use of any additional equipment. A mixing roller within the toner module provides for greater quantity of developer to be stored within the toner module. The disclosed toner module therefore has a greater capacity for storage of developer.
