Image forming apparatus

Abstract

To provide an image formation device that suppresses heating of an exposure device, while securing high manufacturability.SOLUTION: An image formation device comprises: an exposure device; a housing that includes a support member supporting the exposure device; and a cooling device that is configured to flow a coolant in a first direction in a space between the exposure device and the support member. The exposure device has first leg parts and second leg parts each of which line in the first direction and protrudes downward. The support member has, in a plane facing a lower plane of the exposure device: first convex parts that extend in a second direction crossing the first direction and line side by side with the first leg part in the second direction; and second convex parts that extend in the second direction, line side by side with the second leg parts in the second direction, and have a plurality of separated parts in the second direction. The first leg part and the second leg part are away from the support member.SELECTED DRAWING: Figure 4

Claims

[Claim 1] Exposure apparatus and A housing including a support member for the exposure apparatus, A cooling device configured to flow a refrigerant in a first direction into the space between the exposure apparatus and the support member, Equipped with, The exposure apparatus has a first foot portion and a second foot portion, each arranged in the first direction and protruding downwards, The support member, on the surface facing the lower surface of the exposure apparatus, Extending in a second direction intersecting the first direction, the first foot portion and the first convex portion aligned in the second direction, A second convex portion having multiple parts that extend in the second direction, are aligned with the second foot portion in the second direction, and are spaced apart in the second direction, It has, The first foot portion and the second foot portion are separated from the support member. Image forming apparatus. [Claim 2] The support member further has a recess on the opposing surface that extends in the first direction so as to intersect with the second protrusion. The image forming apparatus according to claim 1. [Claim 3] The recess further comprises a sealing member provided on the side surface of the recess. The image forming apparatus according to claim 2. [Claim 4] The upper end of the sealing member is in contact with the lower surface of the exposure apparatus. The image forming apparatus according to claim 3. [Claim 5] The housing has an insertion opening on its side for inserting and mounting the exposure device, The support member is a plate-shaped member positioned substantially horizontally adjacent to the insertion opening, and functions as an insertion guide that guides the insertion of the exposure device when the exposure device is inserted into the housing in the second direction through the insertion opening, by sliding the first foot portion against the first protrusion and sliding the second foot portion against the second protrusion. The image forming apparatus according to claim 1.
