Abstract

An electrophotography apparatus comprises a photosensitive member (11), such as a photosensitive drum, a transfer section, and a toner image bearing film (14) passing by the photosensitive member, and through the transfer section. A charging device (15) uniformly charges the photosensitive member. An exposure device (16) exposes the photosensitive member (11) to a light image thereby to form a latent image. A developing device (17) is disposed facing the toner image bearing film passing by the photosensitive member, for causing toner to be attracted toward the photosensitive member, thereby forming a toner image on the toner image bearing film (14). A paper feed mechanism means feeds a recording paper through the transfer section, at which the toner image is transferred from the toner image bearing film to the recording paper. A fixing device fixes the toner image on the recording paper.
