An end member (30) comprises: a tubular bearing member (40); and a shaft member (50), wherein the shaft member comprises: a shaft-like rotating shaft (51) which is disposed coaxially to the bearing member, and moves in the shaft line direction by rotating around a shaft line with respect to the bearing member; and a tip end member (55) which is disposed coaxially to the rotating shaft, and where a rotating force receiving member (58) provided with an engaging member (60) which engages with a driving shaft (70) of the image forming apparatus main body is disposed at a tip end, wherein a rotating force around the shaft line is transmitted to the rotating force receiving member, the rotating shaft, and the bearing member, in this order, and the rotating force receiving member moves to be inclined with respect to the shaft line.

An end piece for a profiled part is disclosed having a longitudinal axis ZZ, the dimensions of which allow it to be force-fitted into one end of the profiled part, the end piece including at least one cylindrical inner housing for accommodating a rotary adjustment member or a rotary working member in order to rotatably mount the profiled part on a fixed shaft, and the housing being terminated by an inwardly facing wall forming a stop for the rotary adjustment member or rotary working member. The end piece is flexible and includes, on its outer surface, a plurality of fins that project outward and extend longitudinally along the axis ZZ of the inner edge of the end piece in the direction of the outer face of the end piece, the fins being separated by grooves that extend longitudinally along the axis ZZ in the same direction as the fins.
