DEVELOPER, IMAGE-FORMING APPARATUS, AND METHOD FOR FORMING IMAGE

摘要

A developer contains a toner having an external additive deposited thereon. The developer is used with an image-forming apparatus including an image carrier including a surface layer in which fluoropolymer resin particles are dispersed and a cleaning member disposed in contact with an outer surface of the image carrier. The external additive is a nonspherical external additive whose volume average particle size is smaller than the average particle size of exposed portions of the fluoropolymer resin particles in the surface layer of the image carrier.
