PURPOSE:To facilitate maintenance by dividing an replacing a consumption member replacement kit which can be replaced together with a consumption member attachable to and detachable from a device body by uniting members having equal life. CONSTITUTION:A process kit U is divided into a kit A(U-1) and B(U-2), which are attached to and detached from the device body while united by various locking mechanisms. When both kits are combined in one body even after being divided, respective members are held in specific size relation, so there is no trouble to the functions. Then, the kit A contains members such as a developing device and a cleaner part whose life is determined depending upon capacitive factors and the kit B contains members such as an image carrier 4 whose life depends upon the quantity of processed sheets, a secular change, etc., so the respective members are replaced easily without any waste. |
