Image forming apparatus with a surface of a development roller and shell layers of toner particles being formed from a thermosetting resin

摘要

An image forming apparatus uses a developer containing toner particles. The image forming apparatus includes a toner-particle bearing member for bearing the toner particles. Each toner particle includes a toner core containing a binder resin and a shell layer coating a surface of the toner core. The toner-particle bearing member includes a substrate and a surface layer coating a surface of the substrate. The surface layer and the shell layer are each formed from a resin containing a thermosetting resin.
