ABSTRACT:
An image forming apparatus in accordance with the present invention is provided with a unit composed of members such as a photoreceptor drum and an optical system, the unit being attachably and detachably provided with respect to the image forming apparatus main body. With the arrangement, the replacement of the photoreceptor drum can be made at the user's end with ease. It is not necessary to carry out fine adjustments at the user's end for positioning the photoreceptor drum and optical system with respect to the image forming apparatus main body. Thus, professional skill is not required for the replacement of the photoreceptor drum, thereby resulting in that the operations such as maintenance can be effectively made. It is preferable that a cleaner is further provided for removing any contaminated materials adhering to the inner surface of the photoreceptor drum. With the cleaner, the contaminated materials can be removed from the inner surface of the photoreceptor drum, thereby avoiding that the exposure of the photoreceptor drum is not appropriately carried out.
