<p>PURPOSE:To secure sufficient light quantities at end section of the no-image forming marginal section of a photosensitive body and to clear the contour of marginal section of transfer paper, by providing a luminous body inclined at a prescribed angle with the longitudinal direction of the photosensitive drum. CONSTITUTION:A base plate 3 is formed of a platybody having almost the same dimension as the length of a photosensitive drum 1 and a primary charger 6 is provided along the longitudinal direction at the central part of the base plate 3. Plural die-destaticizing lamps 7 and exposure lamps 4 for no-image forming section are provided below and above the primary charger 6, respectively. An exposure lamp 8 for exposing the no-image forming marginal section of the drum 1 is provided inside a cover 5 at an inclined angle of alpha. The light quantity distribution of the lamp 8 is moved toward the margin inside the cover 5 and the light quantity at the marginal section (a) inside the cover 5 can be secured sufficiently.</p> |
