摘要： A novel process cartridge for an image forming apparatus such as for example an electrophotographic copying machine, an image forming apparatus using the novel process cartridge, and a method of manufacturing the novel process cartridge. The cartridge includes a photoconductor unit in which a photoconductor drum is rotatably mounted and a developing unit in which a developing roller is rotatably mounted. A first pair of side plates are formed on the photoconductor unit and rotatably supports both end portions of the photoconductor drum. A second pair of side plates are formed on the developing unit and rotatably supports both end portions of the developing roller. A first pair of pin inserting holes are formed on the first pair of side plates of the photoconductor unit. A second pair of pin inserting holes are formed on the second pair of side plates of the developing unit. A pair of fitting holes are formed on the first or second pair of side plates, and a pair of fitting projections are formed on the pair of side plates without fitting holes. When the photoconductor unit and the developing unit are connected together, the projections elastically fit into the fitting holes, the first and second pairs of side plates are held in surface contact with each other, and the first and second pairs of pin inserting holes overlap each other with their respective centers aligned. A pair of connecting pins is inserted with pressure into the first and second pairs of pin inserting holes once the respective hole centers are aligned.
