PURPOSE:To attain the fatigue recovery of the photosensitive body effectively by a simple method by forming an electrostatic latent image repeatedly on the photosensitive body and carrying out heat treatment in darkness outside a device. CONSTITUTION:An organic photosensitive layer 14 is provided on a conductive substrate 11. The photosensitive layer 14 consists of a charge generating layer 21 and a charge transportation layer 22, or an intermediate layer 13 may; be provided between the substrate 11 and photosensitive layer 14. When the photosensitive body is used repeatedly, a fatigue phenomenon is caused. This photosensitive body is heated up to, preferably, >=40 deg.C and, further preferably, >=55 deg.C in darkness outside the device, so that the photosensitive body recovers from the fatigue. |
