Abstract:
Provided is an electroconductive member for electrophotography capable of charging an electrically chargeable body stably over a long period of time. The electroconductive member includes an electroconductive support and a surface layer on the electroconductive support. The surface layer has a skeleton that is three-dimensionally continuous and a pore that communicates in a thickness direction, and when any region measuring 150 μm per side of a surface of the surface layer is photographed and equally divided into 60 parts in a vertical direction and 60 parts in a horizontal direction to form 3,600 squares, the number of squares including through holes is 100 or less. The skeleton is non-electroconductive and includes a plurality of particles connected to each other through a neck, and an average value D1 of circle-equivalent diameters of the particles is 0.1 μm or more and 20 μm or less.
