PROBLEM TO BE SOLVED: To simply make connection of a photoreceptor unit and the developing unit by an inexpensive structure without increasing the number of components, and without taking labor and time. SOLUTION: The connection of the photoreceptor unit 10 and the developing unit 11 is performed by making an engaging projection 47 formed on a side blade part 11a on one hand side elastically engaged with an engaging hole 41 formed on the side blade part 10a, while bringing the side blade part 11a of the photoreceptor unit 10 into surface contact with the side blade part 11a of the developing unit 11, respectively laying pin inserting holes 40 over 46 formed on the side blade 10a and 11a, and pressurizing/inserting the coupling pin into the pin inserting holes 40 and 46. Thus, the photoreceptor unit 10 and the developing unit 11 can be coupled by an inexpensive structure without increasing the number of components, and without taking labor and time. |
