A roller member includes a cored bar, an elastic layer, and a non-conductive member. The elastic layer is disposed on an outer circumferential face of the cored bar. The cored bar has a projecting portion projecting beyond a range in which the elastic layer is disposed, toward an axial end of the cored bar. The non-conductive member is made of a non-conductive material. The non-conductive member is disposed on the projecting portion. The non-conductive member bites into an end face of an axial end of the elastic layer.
