PURPOSE:To miniaturize an electrophotographic printer by utilizing the internal space of a cylinder of a photosensitive drum, and internally installing an electrifier, a printing head, and a destaticizer. CONSTITUTION:A photosensitive film 2 is applied to the outside surface of a photosensitive drum 1, and the inside is hollow. In this space, the printing head 3, the electrifier 4, and the destaticizer 5 are fixed to a cylinder shaft 6 and installed internally. Each internal parts are provided at a prescribed distance against the photosensitive film 2, by which to the outer periphery of the drum 1, it may suffice that imaging system parts except the internal parts are installed, and accordingly, the printer can be miniaturized. |
