PROBLEM TO BE SOLVED: To improve positional accuracy for positioning a light emitting element array with respect to a drum-like image carrier for efficiently and further accurately exposing the drum-like image carrier, and to eliminate a chance in the positional accuracy of the positioning with respect to the lapse of time for maintaining an excellent image. SOLUTION: The device is provided with the drum-like image carrier 1 and an exposure device 2 having the light emitting element array and an image forming lens 22 transmitting light by the light emitting element array. At this time, the drum-like image carrier 1 is supported by a bearing 11 and a part 28 of the exposure device 2 including the light emitting element array and the image forming lens 22 is abutted on the outer periphery of the bearing 11 to position the exposure device 2 with respect to the drum-like image carrier 1. |
