PROBLEM TO BE SOLVED: To provide an image formation device in which a relative positional accuracy between a light guide member and a light source can be improved.SOLUTION: A printer 1 includes: a device main body 2 including a light source 90; and a drum cartridge 11 attachable to the device main body 2. The drum cartridge 11 includes: a pair of ribs 38; a photosensitive drum 14 extending in a longitudinal direction; and a light guide 18 that guides light for performing static elimination of the photosensitive drum 14 from the light source 90 to a surface of the photosensitive drum 14. The light source 90 includes an insertion portion 94 that engages with the pair of ribs 38 in a state in which the drum cartridge 11 is attached to the device main body 2. The light source 90 is configured to be movable in the longitudinal direction, and is positioned downstream in an attachment direction Y with respect to the light guide 18 in a state in which the drum cartridge 11 is attached to the device main body 2. In a state in which the pair of ribs 38 engage with the insertion portion 94, movement of the light source 90 in the longitudinal direction is regulated. |
