Abstract: 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.
