Optical scanning device including shutter member that closes or opens an emission window and image forming apparatus including the optical scanning device
An optical scanning device, that outputs a light beam through an emission window in an optical housing to scan a surface, may include a shutter member that closes or opens the emission window. The shutter member may include a first opening, that may allow the light beam passed through the emission window to pass the first opening, and a second opening, that may be at a position corresponding to an insertion operation of a cleaning member for cleaning the emission window. The shutter member may include a first opening, that may be on a front surface of the shutter member to allow the light beam passed through the emission window to pass the first opening, and a second opening, that may be on a side surface of the shutter member to allow a cleaning member to be inserted through the second opening for cleaning the emission window.
