ABSTRACT:
A developer for electrophotography is disclosed. The developer comprises a carrier comprising magnetic particles being coated with a fluororesin in which an alkali salt of a fatty acid is contained in an amount of from 0.05 to 0.5% by weight of said carrier, and a toner comprising a colored particle comprising a colorant and a reaction product of a styrene-acryl copolymer having carboxyl groups with a multivalent metal compound, and an inorganic particle containing an ammonium salt-modified polysiloxane. The developer is excellent in the reproducibility of fine line, the density uniformity of solid image and the fine line-reproducibility in copies formed by successive generations and the durability.
