Electrophotographic device

Abstract

Abstract PURPOSE:To use a power source of large capacity by using contact electrostatic charging for charging of a means to be transferred. CONSTITUTION:When a photosensitive drum 1 rotates in the direction as indicated with an arrow B, by following up its rotation, the drum surface part passes through a charging part 2 consisting of corona charge, by which it is to a uniform potential, and also, passes through an exposing part 3, and a latent image corresponding to a shape of an object to be photographed is formed by an exposure. Subsequently, in a developing part 4, what is called a toner carried by a carrier adheres to the surface of the photosensitive drum 1 in accordance with the latent image. Next, in a transfer part 5, the surface part of the photosensitive drum 1 confronts a form to be transferred 9 being ordinary paper and a toner is transferred to the form to be transferred 9, and fixed in a fixing part 8. In this case, before the form to be transferred 9 is carried to the transfer part 5, it is charged by a contact charging means which has been connected to a power source 11, for instance, a charging part 10 for transfer consisting of a conductive brush. In such a way, the charging efficiency to the form to be transferred 9 is improved, therefore, the charging of a prescribed level can be executed by a power source of small capacity.
