Claims

[Claims for Utility Model Registration] (1) An image forming device comprising a lower device main body and an upper body that is rotatable relative to the device main body from a closed state in normal use in a direction to open the device, The image forming unit has an image forming unit that is detachably attached to the upper body, and an exterior cover that is detachable from the upper body for covering the image forming unit after being attached to the upper body, and when the exterior cover is not attached, the image forming unit is detachably attached to the upper body. An image forming apparatus characterized in that the apparatus main body is provided with a rotatable blocking member that prevents the upper body from rotating in a direction from an open state to a closed state with respect to the apparatus main body. (2) The exterior cover has a protrusion in part, and when the upper body is rotated in the direction of the closed state after the exterior cover is attached, the protrusion first contacts the blocking member. The image forming apparatus according to claim 1, wherein the blocking member is rotated downward to release the blocking of the upper body from rotation by the blocking member.
