Abstract
An electrophotographic member having an endless shape comprises: a substrate; and an elastic layer on an outer peripheral surface thereof. The elastic layer contains a silicone rubber and metal silicon fillers dispersed in the silicone rubber. An average of area ratios of the metal silicon fillers in respective first binarized images is 42% or less, and an average of area ratios of the metal silicon fillers in respective second binarized images is 42% or less. The elastic layer has λ of 1.30 W/(m·K) or more, where λ is a thermal conductivity of the elastic layer in a thickness direction thereof, and the elastic layer has ρV of 9.0 LOG Ω·cm or more, where ρV is a common logarithm value of a volume resistivity thereof.
