摘要： A process cartridge which is detachably attachable to an image forming apparatus main body and which has a photosensitive drum is provided with a light guide. This light guide guides light from an LED lamp provided in the image forming apparatus main body to the surface of the photosensitive drum, thus forming a charge removing device for the photosensitive drum. Therefore, it is possible to provide an image forming apparatus and a process cartridge free from image problems, such as lateral stripes and a drum positive ghost, at a low cost.
