摘要： A developer-carrying member to be installed in an electrophotographic developing device for carrying and conveying a developer along a surface thereof, is formed of a substrate, and an intermediate electroless plating layer and an electroplating layer disposed in this order on the substrate. As a result of the electroless and electro double plating layer structure, the developer-carrying member is provided with a wear-resistant surface which has an appropriate degree of roughness suitable for conveying the developer thereon and is yet free from minute projections and cracks undesirable from the viewpoint of continuous image forming performances.

摘要： In a developing method, a layer of electrically charged toner particles is formed on a surface of a developer carrying member, and magnetic particles which retain on their surfaces electrically charged toner particles are dispersed on the surface of the developing carrying member. The toner particles and magnetic particles are carried on the developing carrying member to a developing position where a surface of an electrostatic latent image bearing member for bearing an electrostatic latent image is opposed with a clearance to the surface of the developer carrying member. An alternating electric field is formed at the developing position against the electrostatic image and chains of magnetic particles are formed by stationary magnetic field generating apparatus disposed behind the developer carrying member. The latent electrostatic latent image is developed by the charge toner particles on the surface of the developer carrying member and on the surface of the magnetic particles in the clearance under the alternating electric field and the stationary magnetic field.

摘要： A magnet is disposed in a sleeve for carrying a developer. At a position between two adjacent magnetic poles along the periphery of the magnet, an elastic plate is contacted to the sleeve. The elastic plate is effective to regulate a thickness of a layer of the developer applied on the carrying member. Of the magnetic poles, the magnetic pole disposed upstream of a contact position between the elastic plate and the sleeve with respect to the rotational direction of the sleeve provides a magnetic force F (Gauss). The elastic plate is contacted to the sleeve with the pressure P (g/cm). In this structure, 0.71P+385.ltoreq.F.ltoreq.-1.43P+1630 is satisfied.
