NONMAGNETIC MONOCOMPONENT DEVELOPING TONER

摘要

PURPOSE: To provide a nonmagnetic monocomponent toner which maintains maintain sufficient image density and prevents fog in a non-picture part by decreasing the amount of the toner not transferred on a photoreceptor. CONSTITUTION: In the nonmagnetic monocomponent developer, the toner contains an external additive depositing on the surfaces of the toner particles and the external additive consists of inorganic fine particles (A) having opposite polarity to the toner and subjected to the surface treatment with amino silane and dimethyl polysiloxane and inorganic fine particles (B) having the same polarity as the toner.
