Abstract
An image forming apparatus employing an illuminator configured to irradiate light to a photosensitive body to change a level of electrical potential of the photosensitive body. The illuminator includes at least one light source configured to generate light and a light guide configured to guide the light received from the light source toward the photosensitive body. The light guide includes at least one incidence face and an emission face. The at least one incidence face faces the light source in a main scanning direction to receive the light from the light source into the light guide. The light exits from the light guide through the emission face toward the photosensitive body. The emission face includes a diffusion pattern having a plurality of semi-cylindrical structures along a width direction of the light guide. A radius of curvature of the semi-cylindrical structures increases away from the at least one light source.
