摘要：
An image forming apparatus includes: a photoreceptor drum; a charger for charging an outer surface of the photoreceptor drum; image exposure devices each for exposing the photoreceptor drum to form a latent image thereon, wherein the image exposure devices are provided inside the photoreceptor drum, and are detachably mountable with the photoreceptor drum to the image forming apparatus; a developing device for developing the latent image to form a toner image on the outer surface of the photoreceptor drum; and a supporting member on which the image exposure devices are mounted, wherein the supporting member and the photoreceptor drum are connected through bearing members on both ends of the photoreceptor drum, and the supporting member has an engaging portion for engaging with a part of the image forming apparatus to fix the image exposure devices through the supporting member, while the photoreceptor drum is rotated around the image exposure devices through the bearing members.
