PROBLEM TO BE SOLVED: To improve image quality by preventing an image defect due to oscillation of a photoreceptor drum used for an image forming apparatus. SOLUTION: The photoreceptor drum used for the image forming apparatus is provided with a cylinder 101 in which a electrostatic latent image is formed, a heating element 105 arranged inside the cylinder 101, a control substrate 106 which controls the heating element 105 and a stay member 104 provided over both ends of the rotational axis direction of the cylinder 101 and holds the control substrate 106, wherein the cross section of the stay member 104 approximately in the vertical direction to a rotational axis of the cylinder 101 is made into hollow.
