ELECTROSTATIC CHARGE IMAGE DEVELOPER AND CARRIER

摘要

PROBLEM TO BE SOLVED: To provide an electrostatic charge image developer which is free of scattering of a toner into a developing device and is stable in image density and solid uniformity as a developer for two-component development and enables stable image formation as various characteristics, such as electrostatic chargeability to the toner are less changed with lapse of time even in the case of continuous printing. SOLUTION: The electrostatic charge image developer has the toner containing at least a binder resin and colorant and a carrier, wherein the carrier has a weight average particle diameter≤75μm, has at least a core particle and coating resin and the core particle surface is coated by the coating resin at a ratio of≤80%.
