ることを特徴とする自己走査型露光装置。 In a self-scanning exposure device, the photoreceptor is irradiated with light emitted from a large number of light emitting segments arranged in an array in the main scanning direction through a slit formed in a light shielding member for preventing flare. The light shielding body consists of two light shielding members that are provided to form a slit by sandwiching the light beam irradiated onto the photoreceptor from both sides in the sub-scanning direction, and one of these light shielding members has a reinforcing bend. The photoconductor is provided so that its position can be adjusted so as to move forward and backward relative to the photoreceptor.
A self-scanning exposure apparatus characterized in that the other light shielding member is fixed at a fixed position.
