Developing assembly, process cartridge and image-forming method

摘要

A developing assembly (4) is disclosed having at least a developer container (7), a developer-carrying member (4a) and a developer layer thickness regulation member (4c), wherein the developer (4d) is composed mainly of toner particles containing at least a binder resin and a colorant, and conductive fine particles, and the developer-carrying member (4a) has a substrate (4b) and a surface layer (4a) formed on the substrate (4b) of a non-magnetic metal, an alloy or a metallic compound. Also disclosed are a process cartridge having the developing assembly (4) and the latent-image-bearing member (1) integrally set as one unit detachably mountable on the main body of an image-forming apparatus, and an image-forming method making use of the features of this developing assembly (4).
