    摘要： Provided is an electrophotography member that resists change in performance even if left unused for lengthy periods. The electrophotography member has a base, an elastic layer formed upon the base, and a surface layer covering the surface of the elastic layer and including urethane resin. The electrophotography member is characterized by the urethane resin being a reaction product from: a hydroxyl-terminated prepolymer obtained by reacting a polyester polyol and a polyisocyanate; and a isocyanate-terminated prepolymer obtained by reacting a polyester polyol and polyisocyanate.

    摘要： Provided is a developer carrier which is capable of stably forming high-quality images even in cases where a recording paper containing much talc is used. This developer carrier comprises a conductive substrate and a surface layer that is arranged on the substrate and contains a resin. The surface layer has a thickness of from 1.0 µm to 100.0 µm (inclusive); the Martens hardness at an indentation depth of 0.1 µm as determined by pressing a Vickers indenter into the surface layer from the outer surface in the thickness direction is from 50.0 N/mm2 to 100.0 N/mm2 (inclusive); the Asker C hardness as determined from the outer surface of the surface layer is from 75° to 90° (inclusive); and the value of the work function of the outer surface of the surface layer is from 5.6 eV to 6.0 eV (inclusive).

    摘要： A developing method is provided in which a developer is carried on a developer carrying member, a thin layer of the developer is formed thereon and a latent image on a latent image bearing member is developed with a developer. The developer is composed of magnetic toner particles containing a binder resin and a magnetic powder. The magnetic powder has a saturation magnetization of 67.0 Am 2 /kg to 75.0 Am 2 /kg in a magnetic field of 79.6 kA/m (1,000 oersteds) and has a residual magnetization of 4.5 Am 2 /kg or less. In the surface profile of the conductive resin coat layer of the developer carrying member, the relationship 1.00 ≤ S/A ≤ 1.65 is satisfied where S is a surface area of regions zoned by an area A of microscopic unevenness regions from which parts exceeding a reference plane by 0.5 × r (r: weight average particle diameter (µm) of a toner used) or more have been excluded.
