摘要： A cleanerless cartridge in which a photoconductor body and a charger are integrated, and a cleaner-equipped cartridge in which a photoconductor body, a charger and a cleaner are integrated are prepared. An image forming apparatus body is configured such that the cartridges are attachable to first- to fourth-stage image forming sections. When the cleanerless cartridge is attached to the first- to fourth-stage image forming sections, an image forming operation is controlled under an image formation condition for a cleanerless process. When the cleaner-equipped cartridge is attached to the first- to fourth-stage image forming sections, an image forming operation is controlled under an image formation condition for a cleaner-equipped process.
