Abstract:
1. An image forming apparatus comprising: a main body; and a cover member holding an optical scanning device and supported on the main body in such a manner as to be pivotable between a predetermined open position and a predetermined closed position, wherein: the optical scanning device has a light source for emitting laser light, a shutter member which is displaceable between an optical path closing position for closing an optical path of the laser light and an optical path opening position for opening the optical path, a housing accommodating the light source and the shutter member therein and having an opening at a bottom surface facing the main body, and a dustproof member having elasticity; the main body has a contact member which is capable of coming into contact with the shutter member through the opening and which becomes positioned away from the shutter member to cause the shutter member to assume the optical path closing position when the cover member assumes the open position while coming into contact with the shutter member to cause the shutter member to assume the optical path opening position when the cover member assumes the closed position; the shutter member includes a closing portion which closes the opening from inside the housing when the shutter member assumes the optical path closing position; and the dustproof member is disposed on an outer side of the housing in such a manner as to extend around the opening and is configured to press against an entire periphery of the contact member when the cover member assumes the closed position.
