<p>PROBLEM TO BE SOLVED: To prevent a thermal deformation of a line-shaped recording means by heat from a heating body and to highly accurately register the means by fixing the recording means at a central part onto a supporting body in writing images with the line-shaped recording means fixed on the supporting body. SOLUTION: A charging means for impressing a uniform potential to a photosensitive body drum 10 is set along an outer circumference of the photosensitive drum 10, and moreover an exposing optical system 12 as a line-shaped recording means is set for every color along an inner circumference of the drum 10. The exposing optical system 12 consists of an LED array module (exposing element) 12a and a light-transmitting body (image-forming element) 12b having light- converging properties. The exposing optical system is mounted to a predetermined set position at a central part of a supporting member 20 using a pipe- shaped hollow member of aluminum or the like via a spacer block 12e and an auxiliary block 12f by an adhesive. Since the exposing optical system 12 is supported to the pipe-shaped supporting member 20, the apparatus can be light-weight and low in heat capacity.</p> |
