Abstract
Official abstract text for this publication.
An electrophotographic member comprises a base member and an elastic layer on the base member. The elastic layer contains a silicone rubber, an ionic electroconductive agent, and an inorganic particle, and the inorganic particle contains a hydroxide of at least one of magnesium or aluminum, and has a silicon atom on a surface thereof in an amount of 0.50 to 2.00 atomic %. An aqueous dispersion of which 5 mg of the inorganic particle is dispersed in 10 ml of water has a turbidity of 200 NTU or more and 1,240 NTU or less.
First claim
Opening claim text (preview).
What is claimed is: 1. An electrophotographic member, comprising: a base member; and an elastic layer on the base member, the elastic layer comprising a silicone rubber, an ionic electroconductive agent and an inorganic particle, wherein the inorganic particle contains at least one hydroxide of magnesium or aluminum, the inorganic particle has a silicon atom on a surface thereof in an amount of 0.50 to 2.00 atomic %, and when an aqueous dispersion of 5 mg of the inorganic particle and 10 ml of water is prepared, the aqueous dispersion has a turbidity of 200 to 1,240 NTU. 2. The electrophotographic member according to claim 1 , wherein the elastic layer contains 5.0 to 30.0 parts by mass of the inorganic particle with respect to 100 parts by mass of the silicone rubber. 3. The electrophotographic member according to claim 1 , wherein the aqueous dispersion has a turbidity of 290 to 1,200 NTU. 4. The electrophotographic member according to claim 1 , wherein the electrophotographic member has a cylindrical or a columnar shape. 5. The electrophotographic member according to claim 1 , wherein the electrophotographic member is an electrophotographic belt having an endless shape. 6. An electrophotographic image forming apparatus, comprising: an electrophotographic member configured to function as an intermediate transfer member, the intermediate transfer member having a base member bearing an elastic layer, the elastic layer comprising a silicone rubber, an ionic electroconductive agent and an inorganic particle, wherein the inorganic particle contains at least one hydroxide of magnesium or aluminum, the inorganic particle has a silicon atom on a surface thereof in an amount of 0.50 to 2.00 atomic %, and when an aqueous dispersion of 5 mg of the inorganic particle and 10 ml of water is prepared, the aqueous dispersion has a turbidity of 200 to 1,240 NTU.
