An electrostatic copying apparatus comprises a photosensitive drum (36) including a drum body (58) and a photosensitive layer provided around the outer peripheral surface of the drum body, a supporting mechanism (60) for rotatably and detachably supporting the photosensitive drum, and paripheral devices (38, 42, 44, 46) which are in contact with the outer peripheral surface of the photosensitive drum at a contact force of 50 g. The drum body is formed of a thin metal tubular body of which the strength per unit length is 2.4 Kg/mm or less, whereby the said drum body when it has been removed from the supporting mechanism may be crushed by foot. |
