Abstract
It is an object of the present invention to provide an electroconductive member for electrophotography capable of suppressing image density unevenness caused by the adhesion of foreign matter. Provided is an electroconductive member for electrophotography, including at least: an electroconductive support, and a surface layer formed on an outer side of the electroconductive support, in which the surface layer includes a porous body, and in which the porous body satisfies the following conditions (1) to (3): (1) the porous body has a co-continuous structure including at least a skeleton that is three-dimensionally continuous and a pore that is three-dimensionally continuous; (2) the porous body has electroconductivity; and (3) an average diameter of a maximum inscribed circle of an opening of the pore on a surface of the porous body is 3 μm or more and 8 μm or less.
