Luminous flux from a large number of light emitting segments arranged in an array in the main scanning direction on a support plate is irradiated onto a photoreceptor through a slit formed in a light shielding member for preventing flare. - In a self-scanning exposure device adapted to perform exposure, the thickness of the portion of the support plate that is close to the photoreceptor is tapered so that it becomes thinner as it approaches the photoreceptor; . A self-scanning exposure apparatus, characterized in that the thickness of the support plate is increased in a portion other than the tapered portion so as to prevent a decrease in rigidity of the support plate. 2 Self-scanning in which the light emitting flux from a large number of light emitting segments arranged in an array in the main scanning direction on a support plate is irradiated and exposed onto a photoreceptor through a slit formed in a light shield for preventing flare. In the type exposure apparatus, the light shielding body is attached to the side of the photoconductor, and the light shielding body is provided so as to be adjustable in reciprocating movement in the sub-scanning direction, which is the direction in which the photoconductor is transported. Scanning exposure equipment.
