IMAGE FORMING SYSTEM

摘要

The presently disclosed embodiments relate generally to image forming systems comprising imaging apparatus members and toner compositions. More specifically, the present embodiments relate to specific toner compositions for use with electrophotographic imaging members comprising an overcoat layer protecting the imaging member surface and a contact type charging device, such as a “bias charge roll” (BCR). The toner compositions comprise a combination of additives that provide an image forming system that does not suffer from the commonly observed deletion and imaging member wear issues.

主权项

1. A method for forming images comprising
providing a toner composition into an image forming apparatus, the image forming apparatus comprising
an imaging member having a charge retentive-surface for developing an electrostatic latent image thereon, wherein the imaging member comprises:a substrate,one or more photoconductive layers disposed on the substrate, andan overcoat layer disposed on the one or more photoconductive layers, and a charging unit comprising a charging roller disposed within charging distance of the surface of the imaging member and the toner composition comprising toner parent particles, and one or more additives comprising zinc stearate having a particle size about 4 to about 8 μm and polymethylmethacrylate having a particle size of from about 0.35 to about 0.2 μm; charging the charge retentive-surface with the charging roller; exposing the charge-retentive surface to a light pattern of an original image to selectively discharge the charge-retentive surface and form an electrostatic latent image; developing the electrostatic latent image with the toner composition to form a toner image; and transferring the toner image to a substrate.
