ABSTRACT:
An optical recording apparatus includes an imaging member which is advanced along a predetermined path, an optical recording head for applying light containing image information to the imaging member to form an electrostatic latent image thereon, a developing unit for developing the latent image thereby converting it into a toner image and a transfer unit for transferring the toner image to a sheet of transfer paper. With the imaging member in the form of a belt, a back-up member and a contact member, preferably in the form of brush, are provided on both sides of the belt-shaped imaging member in the vicinity of an image exposing section where the light from the recording head is applied to the imaging member thereby allowing that portion of the imaging member which is located in the image exposure section is prevented from moving up and down with respect to the advancing direction of the imaging member.
