Abstract
An apparatus in which an contaminants are removed from an electrode positioned between a donor roller and a photoconductive surface. A magnetic roller is adapted to transport developer material to the donor roller. The electrode is vibrated to remove contaminants therefrom.
Claims21
An apparatus for removing contaminants from an electrode member positioned in a space between a surface adapted to have a latent image recorded thereon and a donor member, including:
- means for vibrating said electrode member to remove contaminants therefrom;
- and
- means for advancing developer material to said donor member, said advancing means being inoperative in response to said vibrating means being energized.
An apparatus for removing contaminants from an electrode member positioned in a space between a surface adapted to have a latent image recorded thereon and a donor member, including:
- means for vibrating said electrode member to remove contaminants therefrom, said vibrating means includes means for electrically biasing said electrode member;
- and
- means for advancing developer material to said donor member, said advancing means being inoperative in response to said vibrating means being energized.
An electrophotographic printing machine of the type in which an electrostatic latent image recorded on a photoconductive member is developed to form a visible image thereof, wherein the improvement includes:
- a housing defining a chamber storing a supply of developer material comprising at least carrier and toner;
- a donor member spaced from the photoconductive member and being adapted to transport toner to a region opposed from the photoconductive member;
- an electrode member positioned in a space between the photoconductive member and said donor member;
- means for vibrating said electrode member to remove contaminants therefrom;
- and
- a transport member, located in the chamber of said housing, adapted to advance developer material from the chamber of said housing to said donor member.

- an electrode member positioned in the space between the photoconductive member and said donor member;
- means for vibrating said electrode member to remove contaminants therefrom said vibrating means is inoperative in response to said transport member advancing developer material to said donor member;
- and
- a transport member, located in the chamber of said housing, adapted to advance developer material from the chamber of said housing to said donor member.
