Abstract

Disclosed is a single layer fluorocarbon elastomer intermediate transfer member for use in electrostatographic printing machines. The single layer fluorocarbon elastomer possesses requisite strength, electrical semiconductivity, and conformability to an image receiving substrate for an intermediate transfer member. The single layer intermediate transfer member is also able to achieve substantially 100% toner transfer to an image receiving substrate in a process in which images are produced utilizing a plurality of imaging stations.

Disclosed is a single layer fluorocarbon elastomer intermediate transfer member for use in electrostatographic printing machines. The single layer fluorocarbon elastomer possesses requisite strength, electrical semiconductivity, and conformability to an image receiving substrate for an intermediate transfer member. The single layer intermediate transfer member is also able to achieve substantially 100% toner transfer to an image receiving substrate in a process in which images are produced utilizing a plurality of imaging stations.

Also disclosed is the use of a single layer fluorocarbon elastomer intermediate transfer member in an apparatus having a single imaging station, including systems in which each color is transferred to the intermediate transfer member prior to exposing and developing succeeding colors of the image and also systems in which each color is exposed and developed on the imaging member on top of preceding developed color images on the imaging member.

The transfer member and transfer method thereof may be used in an apparatus for transferring a toner image from a plurality of 6e., at least two) imaging stations to an image receiving substrate employing a single layer fluorocarbon elastomer intermediate transfer member. The intermediate transfer member does not require rigidity in order to maintain registration and prevent image shifting, color shifting or color degradation of the multi- image upon the intermediate transfer member. The intermediate transfer member is a single layer which possesses excellent strength, thermal conductivity and electrical semiconductivi ty. The intermediate transfer member material is resistant to attack from toner or developer materials and withstands exposure to the electrical, mechanical and thermal environment of a printing apparatus. The fluorocarbon elastomer is, for example, as sold under the tradename Won@, available from E.I. du Pont de Nemours & Co. Suitable fluorocarbon elastomers include copolymers and terpolymers of vinylidene fluoride, hexafluoropropylene, tetrafluoroethylene, chlorotrifluoroethylene and propylene, including vinylidene fluoride/hexafluoropropylene copolymers and vinylidene fluoride/hexafluoropropylene/tetrafluoroethylene terpolymers such as those sold by E.I. du Pont de Nemours & Co. as Viton GF, Viton GFLT, Viton E- 600C,...
