PURPOSE:To reduce the cost and to prevent alteration and to shorten the time spent in continuous printing and issuing of many tickets, by using an electrophotographic printing mechanism capable of printing information on an ordinary paper. CONSTITUTION:A photoconductive photosensitive layer on the surface of a photosensitive drum 1 is formed of amorphous silicon especially. An electrically charged part 2 electrifies the surface of the photosensitive drum uniformly with plus static electricity by corona discharge, and photosensitivity is given to the photosensitive drum by this electrostatic charge. An exposure part 3 consists of a light emitting head 3a, where light emitting elements such as light emitting diodes (LED) or the like are arranged linearly, and a converging optical transmitting body 3b having many rod lenses (CL) which converge luminous fluxes from individual light emitting elements of the light emitting head individually and transmit them so that they are focused on the surface of the photosensitive drum. A developing part 4 applies a potential equal to the charging potential of the electrically charged part to attract a black toner, which is electrified with plus electricity, to a latent image of zero potential on the photosensitive drum by the electric field force. |
