Abstract

A carrier for developing electrostatic latent images has an excellent charging stability, resistance to spenting, and durability and can provide high resolution images over long periods of operation. The carrier achieves these advantageous effects because it contains a pendant carbosiloxane dendrimer-functional vinyl-type polymer. A toner for developing electrostatic images also contains the pendant carbosiloxane dendrimer-functional vinyl-type polymer. The toner has an excellent fluidity, releasability, fixing behavior, resistance to offset, and flexibility and can provide high resolution images. The toner and carrier can be used in various imaging technologies, e.g., electrophotographic technologies, electrostatic recording technologies, and electrostatic printing technologies. An electrophotographic photoreceptor contains, in at least its surface layer, a binder resin and the pendant carbosiloxane dendrimer-functional vinyl-type polymer.
