TONER FOR FORMING ELECTROPHOTOGRAPHIC IMAGE AND ELECTROPHOTOGRAPHIC IMAGE FORMING METHOD

摘要

PURPOSE: To provide a toner capable of ensuring a stable quantity of electric charges over a long period of time in an image forming method by which devel opment is carried out with a developer layer kept in noncontact with a photoreceptor and capable of maintaining stable electrostatic chargeability independently of an environmental change and to provide an electrophotographic image forming method. CONSTITUTION: In this toner obtd. by adding at least fine resin particle and inorg. fine particles to colored particles consisting essentially of a resin and a colorant, the fine resin particles are made of a melamine-formaldehyde condensation polymer and have 0.01-1.0μm vol. average particle diameter and the inorg. fine particles have 0.01-0.20μm vol. average particle diameter. The standard deviation of the vol. average particle diameter distribution of the inorg. fine particles is 10-30.
