Abstract:
Provided is an electrophotographic rotatable pressing member having further durability. The electrophotographic rotatable pressing member includes: a substrate; and an elastic layer formed on the substrate, the elastic layer containing a silicone rubber and a needle-shaped filler dispersed in the silicone rubber and having hollow parts, wherein, when cutting the elastic layer along a cross section including a center axis of the substrate in a longitudinal direction of the electrophotographic rotatable pressing member, and a total of each sectional area of the hollow parts in a unit area A2 of a cross-sectional surface is defined as A1, a standard deviation of an area ratio A1/A2 is 0.08 or less.
