ABSTRACT:
An image forming apparatus shown has a developing unit and a photoconductor unit both of which are disposed in a body. The developing unit and photoconductor unit are slidably mounted adjacent to each other within the body. The mounting and positioning of the units are such as to allow the developing unit and the photoconductor unit to be successively pulled out of the body. The apparatus further includes an urging member which allows the photoconductor unit to be urged toward the developing unit. The body includes upper and lower housings and is designed so that the upper housing can be swung upward about a fulcrum on one side of the body and thereby form an opening between the upper and lower housings on the other side of the body. The apparatus is designed and the components are configured such that when the developing unit is pulled out of the body the photoconductor unit moves toward the opening and the photoconductor unit can be replaced in a large open space near the opening.
