PURPOSE:To simplify structure, by providing 2 air paths in order to cool both lamps for imagewise exposure before charging using only one fan. CONSTITUTION:Air sucked with a cooling fan 30A flows through an air B to cool an imagewise exposure lamp 21, and moreover, through another air path C to cool an exposure lamp 28 for illuminating photo-sensitive drum 18 before charging. In addition, light emitted from the lamp 21 is prevented from reaching the drum 18 by providing a partition board 32. |
