    摘要: A developing roller is provided, which is particularly used in an image forming apparatus of a highly durable design and is free from toner leakage even after formation of a predetermined number of images. Opposite end regions (5a) of an outer peripheral surface (5) of a roller body (2) of the developing roller (1) to be respectively kept in sliding contact with seal members each have a friction coefficient μ of not greater than 0.15.

    摘要: An inventive developing roller is adapted for use in an electrophotographic image forming apparatus. The developing roller includes a roller body. At least an outer peripheral surface of the roller body is formed from a rubber composition containing a base rubber. The base rubber contains a styrene butadiene rubber in a proportion of not less than 10 mass % and not greater than 70 mass % based on the overall amount of the base rubber. The outer peripheral surface of the rubber body has a surface roughness Ra of not less than 0.78 μm and not greater than 1.8 μm.
