PROBLEM TO BE SOLVED: To provide a photoreceptor drum which can efficiently transmit heat of a sheet-like heater and is inexpensive. SOLUTION: The photoreceptor drum 11 is constituted by curving and arranging a sheet-like heater 3 having elastic force in an extension direction so as to come into contact with an inner peripheral surface 2 of a photoreceptor drum 1. One end edge 5 extending in axial direction A of the drum of the sheet-like heater 3 and other end edge 6 are connected to each other. The sheet-like heater 3 forms a circular shape in section as a whole and is brought into face to face contact with the inner peripheral surface 2 by its own elastic force. The heat is efficiently transmitted to the photoreceptor drum 1, so that the number of components can be reduced. For example, tongue pieces 11 of the one end edge 5 and the other end edge 6 may be alternately combined one above the other. The one end edge 5 and the other end edge 6 may extend to the central side of the drum and may have bent parts 12 abutting on each other. The thin one end edge 5 may be fitted into the groove 17 of the other end edge 6. COPYRIGHT: (C)2006,JPO&NCIPI |
