Abstract

PURPOSE:To prevent early fading of a fixed toner image by incorporating specific toner particles and fine particles contg. a UV absorbent and/or antioxidant into the title developer. CONSTITUTION:The electrostatic developer is constituted by using a binder resin, the toner particles contg. a dye and/or pigment and the fine particles contg. the UV absorbent and/or the antioxidant as essential components. Namely, this developer contains the fine particles contg. the UV absorbent and/or the antioxidant and, therefore, the film by the UV absorbent and/or the antioxidant is formed on the surface of the unfixed toner image at the time of fixing the unfixed toner image. The deterioration of the dye and/or pigment is, therefore, effectively prevented. The early fading of the fixed toner image is thereby prevented.
