    摘要： In a developing assembly, a process cartridge and an image-forming method, a specific developer and a specific developer-carrying member are used in combination. The developer comprises toner particles containing at least a binder resin and a colorant, and conductive fine particles; the toner particles having a Circularity a of less than 0.970 as found from the following expression: Circularity a = L 0 /L where L 0 represents the circumferential length of a circle having the same projected area as a particle image, and L represents the circumferential length of a projected image of a particle.
    The developer-carrying member has at least a substrate and a resin coat layer formed on the substrate; the resin coat layer containing at least a coat layer binder resin and a positively chargeable material.

    摘要： A developing assembly is disclosed having at least a developer container, a developer-carrying member and a developer layer thickness regulation member, wherein the developer is composed mainly of toner particles containing at least a binder resin and a colorant, and conductive fine particles, and the developer-carrying member has a substrate and a surface layer formed on the substrate of a non-magnetic metal, an alloy or a metallic compound. This developing assembly causes no sleeve ghost, enables electrostatic latent images to be faithfully developed, causes no fading phenomenon, and enables high-density images to be formed in every environment. Also disclosed are a process cartridge having the developing assembly and the latent-image-bearing member 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.
