    摘要： In a developer carrying member used in a developing apparatus by means of which an electrostatic latent image formed on an electrostatic latent image bearing member is developed with a developer to render it visible, the developer carrying member has at least a substrate and a resin coat layer formed on the substrate surface, and the resin coat layer contains at least a binder resin and graphitized particles. The surface of the resin coat layer has an average value A and a standard deviation σ of 100 ≤ A ≤ 800 (N/mm 2 ) and σ 2 ), respectively.

    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.
