    • An electro-photographic image forming apparatus with an improved mounting structure of an LSU(Laser Scanning Unit) is provided to be slimmed and be light in weight by disposing the LSU to occupy a part of a path through which a developing machine is passed and lowering the height of a body. A frame(110) is formed as an external shape of a body. A developing machine(120) is mounted in the body through a movement path formed in the frame(110). One side of an LSU(130) is rotatably combined to the frame(110), and a free end part of the other side of the LSU(130) is disposed to enter the movement path of the developing machine(120). A door(140) is installed in the body to open and close a gateway connected with the movement path. An interlocking device(150) connects the free end part of the LSU(130) with the door(140). When the door(140) is opened, the interlocking device(150) interlocks the LSU(130) so that the free end part of the LSU(130) is lifted out of the movement path when the LSU(130) is rotated.

    • PURPOSE: A window cleaning apparatus of a laser scanning unit is provided to prevent attachment of a foreign substance to the window of the laser scanning unit, thereby forming normally an electrostatic latent image of a photosensitive drum and then enhancing the image quality. CONSTITUTION: An air duct(90) is mounted to both sides of a window(71) of a laser scanning unit(70). An inlet of the air duct is positioned at a side of a fan(80) so that air blown by rotation of the fan is supplied to inside of the air duct. The laser scanning unit comprises a driving motor(75) and a rotation polyhedral mirror(74) rotated by the driving motor. A laser diode(77) is attached to a side of the laser diode. Laser reflected to the rotation polyhedral mirror passes through the first and second focus lenses(72,73) and then the passed laser is reflected by a reflective mirror and passes through the window. Plural air duct holes(92) are formed at the air duct toward the window.
