Abstract
Provided is a member for electrophotography that enables stable formation of a high-quality electrophotographic image even when used as a developing member over a long period of time. The member for electrophotography includes: a support; an electro-conductive elastic layer on the support; and a plurality of electrically insulating domains on the electro-conductive elastic layer, in which a surface of the member for electrophotography includes surfaces of the electrically insulating domains and an exposed portion of the electro-conductive elastic layer free of being covered by the electrically insulating domains, and in which the electrically insulating domains each contain a resin having a specific structure.
