An image forming apparatus includes a light source, a cleaning portion, and a light guide member. The light source irradiates an image carrying member with light to remove electricity from a surface of the image carrying member after formation of an electrostatic latent image thereon. The cleaning portion cleans the surface of the image carrying member. The light guide member is disposed on an upstream side of the cleaning portion in a rotation direction of the image carrying member, forms a light guide path for guiding the light irradiated from the light source to the image carrying member, and includes at least one reflection surface, wherein an area of the reflection surface on the image carrying member side is lower in reflection ratio than an area of the reflection surface on the light source side.
