PROBLEM TO BE SOLVED: To provide a toner for recycling system which can maintain a sufficient image density and which is free from problems of a fog or toner scattering even when continuous copying on many sheets is carried out in a recycling system or copying is carried out in various environments, and to provide a recycling development method by using the toner. SOLUTION: The toner for recycling system consists of toner particles containing at least a cycloolefin copolymer resin as a binder resin and at least a polypropylene wax as a release agent, and 0.1 to 1.5 wt.% silica fine particles depositing on the surface of the toner particles. The toner is used for the recycling development method so that the toner remaining on the photoreceptor surface is collected, returned to the developing device and reused. |
