Abstract
The invention provides a toner which can maintain sufficient image density upon continuous copying in a recycle system even under any environmental conditions without causing troubles such as fogging and toner dusting. The toner for recycle system comprises toner particles which contain, as a binder resin, at least a cycloolefin copolymer resin and, as a releasing agent, at least a polypropylene wax, and fine silica particles adhered to the surface of said toner particles. This toner is used for a toner recycling type developing method, in which the toner remaining on the surface of the photosensitive member is recovered into the developing device and is reused.
