PURPOSE:To prevent the deterioration in image quality and drop-out by providing a light shielding plate so that the irradiation of the luminous flux from a light source to an image region is prevented. CONSTITUTION:The greater part of the luminous flux irradiated by the light emitting chip of an LED7 arrives at an image carrying body 3 and is irradiated on the parts B, C in the non-image region. Part of the luminous flux from the LED7 radiated on the image region D is shielded by the light shielding plate 13 and it thus prevented from arriving at the region D. The light from adjacent LEDs 7, 7' is superposedly irradiated on the non-image regions B, C positioned at the intermediate of the adjacent LEDs 7, 7'. The destaticization of the non-image regions B, C is executed by the luminous flux from the LEDs 7, 7'. |
