PROBLEM TO BE SOLVED: To reduce the number of parts so as to reduce cost by forming a carrying path by partitioning with the unit case of a photoreceptor unit, thereby eliminating the need for extra parts, such as a carrying pipe and a duct, which form the carrying path. SOLUTION: A cleaner 14 is provided in a higher position than a developing device 12. A residual-toner discharge port through which residual toner is discharged from the cleanser 14 and a toner recovery port through which residual toner is returned to the developing device 12 are connected by the carrying path formed by partitioning with the unit case 40 of the photoreceptor unit A. The residual toner discharged from the residual-toner discharge port is allowed to fall naturally by its weight, then carried, and recycled by being put into the developing device 12 from the toner recovery port. |
