1. An image forming apparatus comprising:
a laser scanning unit having a dust-tight light window adapted to pass a laser beam for forming an electrostatic latent image on a photosensitive medium in response to an image signal,
wherein the image forming apparatus includes a contamination prevention member, which is removably attached to and covers substantially the entire top surface of the light window with one side exposed to an outside of a main body, which prevents a contamination material from getting onto the light window, and which a user can recognize and remove easily, and which must be removed from the light window prior to a first use of the image forming apparatus by a user.
