ELECTROSTATIC LATENT IMAGE DEVELOPING CARRIER AND ELECTROSTATIC LATENT IMAGE TWO-COMPONENT DEVELOPER

摘要

PURPOSE:To provide the electrostatic latent image developing carrier and two- component developer which are free from surface staining of image and splashing of toners and obviate the degradation in image quality by an edge phenomenon and charge accumulation. CONSTITUTION:The electrophotographic developing carrier is the electrostatic latent image developing carrier which has a silicone resin coating layer contg. an org. tin compd. or silane coupling agent and conductive fine powder. The value of the ratio Si-C/Si-0 of the Si-C bonds in this silicone resin coating layer and the Si-0 bonds therein is in a range from 0.15 to 0.35.
