Abstract:
1. An image forming device comprising: a main casing; a plurality of photosensitive bodies each defining a longitudinal direction, and arrayed with a space between neighboring photosensitive bodies in an array direction perpendicular to the longitudinal direction; a photosensitive unit movable relative to the main casing and including the plurality of photosensitive bodies; an exposure unit disposed in the main casing and confronting the photosensitive unit in a confronting direction perpendicular to the longitudinal direction and the array direction, the exposure unit being configured to expose the photosensitive bodies to light; wherein the main casing comprises a first side plate supporting the exposure unit and having a first primary portion extending in the array direction, the first side plate also having a first positioning portion and a second positioning portion spaced away from the first positioning portion in the array direction; wherein the photosensitive unit comprises a second side plate supporting the photosensitive bodies and having a second primary portion extending in the array direction, the second side plate also having a third positioning portion subjected to positioning relative to the first positioning portion, and a fourth positioning portion subjected to positioning relative to the second positioning portion, the first positioning portion and the third positioning portion being overlapped with each other at a first overlapped position and the second positioning portion and the fourth positioning portion being overlapped with each other at a second overlapped position, in the longitudinal direction while the first primary portion and the second primary portion being spaced away from each other, a distance between the second overlapped position and the exposure unit in the confronting direction being smaller than a distance between the first overlapped position and the exposure unit in the confronting direction.
