ELECTROSTATIC LATENT IMAGE DEVELOPING CARRIER, NEGATIVE CHARGE TYPE DEVELOPER AND IMAGE FORMING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an electrostatic latent image developing carrier which ensures a small change in the fluidity of a developer in an early stage of actual printing, has higher durability and gives good image quality over a long period of time while using a carrier coated with a nitrogen-containing additive added silicone resin and to provide a developer using the carrier and an image forming method. SOLUTION: In the electrostatic latent image developing carrier obtained by coating magnetic material particles with a silicone resin, the silicone resin contains at least a nitrogen-containing coupling agent, the number % of surface nitrogen atoms after the post-treatment of the carrier is 0.2-1.5% and the thickness of the coating layer is 0.2-2.0μm.
