20200117127 | ELECTROPHOTOGRAPHIC MEMBER AND FIXING DEVICE - An electrophotographic member including: a base member; an elastic layer having a thickness of from 100 μm to 500 μm, and containing a cured product of an addition-curable silicone rubber composition; and a cured product layer arranged between the base member and the elastic layer, the cured product layer containing a cured product of a composition containing an organopolysiloxane having a Si—H group and a silane coupling agent having an alkenyl group. A peel adhesive strength between the elastic layer and the base member is a specific range. The elastic layer undergoes a cohesive failure in a peel test from the base member. The ratio (HU2/HU1) of a universal hardness HU2 on the inner surface of the elastic layer to a universal hardness HU1 at a position reached by cutting the elastic layer from its outer surface in its depth direction by 10 μm is a specific range. | 2020-04-16 |
