Abstract
Official abstract text for this publication.
Provided is an electrophotographic member for an electrophotographic apparatus, which suppresses the occurrence of a banding image caused by uneven charging. The electrophotographic member includes: an electroconductive substrate; and a surface layer, in which: the surface layer includes a binder resin and an aggregate of at least one crystal particle selected from the group consisting of a flaky crystal particle of magnesium carbonate and a flaky crystal particle of calcium carbonate; an edge face of a card house structure formed of the crystal particle is exposed at a surface of the aggregate; a surface of the surface layer includes a convex portion derived from the aggregate; and a surface of the convex portion has unevenness reflecting a shape of the edge face of the card house structure exposed at the surface of the aggregate.
