Abstract
An image-bearing member especially adapted to a very compact electrophotographic apparatus is provided. The image-bearing member has a ratio of the diameter to the length of 1:5 or more, and the surface of the image-bearing member has a relative frictional coefficient against urethane rubber of 0.7 or less with polyethylene terephthalate film as the standard, whereby a cleaning failure and generation of blade scratches on the image-bearing member can be avoided even if it has a small diameter of 45 mm or less. The cleaning effect is ensured if the cleaning blade line pressure is 7 g/cm or higher.
