摘要

The present invention provides an exposure apparatus Award ( ) as a challenge to maintain high accuracy position to decide about the body the . ; first direction of orientation of the rotation axis of the photosensitive drum (12) (Z -direction) and a second direction orthogonal to the first direction (Y direction) and the first direction and the second direction As for the direction in which the plurality of third direction (X direction) perpendicular to the sides of , the LPH (14) protruding from the second projecting member (252F, 252R) brought into contact with the photosensitive drum by a plurality of positions in the 12 for and an LPH (14) XZ direction for locating the support member (123F, 123R).
