Abstract
An apparatus which develops a latent image recorded on an image receiving member with developer material. A donor roll is positioned in a chamber of a housing having a supply of developer material therein. The donor roll transports a metered layer of developer material into contact with the latent image to develop the latent image. A rotating and translating brush gently disturbs the metered layer of developer material on the donor roll. This substantially prevent the accumulation of developer material agglomerates on the donor roll so as to create a more stable, uniform developer material layer for development of the latent image therewith.
Claims14
An apparatus for developing a latent image recorded on an image receiving member, including:
- a housing defining a chamber storing a supply of developer material therein;
- means, disposed at least partially in the chamber of said housing, for transporting a metered layer of developer material;
- and
- means for disturbing the metered layer of developer material on said transporting means to prevent accumulation of developer material agglomerates on said transporting means creating a substantially stable, uniform layer of developer material thereon for developing the latent image recorded on the receiving member therewith, said disturbing means includes a brush having a multiplicity of fibers extending outwardly therefrom in contact with the metered layer of developer material on said transporting means, said brush being adapted to rotate and translate so as to disturb the metered layer of developer material by gently brushing thereagainst.
An electrophotographic printing machine of the type having an electrostatic latent image recorded on a photoconductive member, wherein the improvement includes:
- a housing defining a chamber storing a supply of developer material therein;
- means, disposed at least partially in the chamber of said housing, for transporting a metered layer of developer material;
- means for disturbing the metered layer of developer material on said transporting means to prevent accumulation of developer material agglomerates on said transporting means creating a substantially stable, uniform layer of developer material thereon for developing the electrostatic latent image recorded on the photoconductive member therewith, said disturbing means includes the brush having a multiplicity of fibers extending outwardly therefrom in contact with the metered layer of developer material on said transporting means, said brush being adapted to rotate and translate so as to disturb the metered layer of developer material by gently brushing thereagainst.
