Abstract: A developing cartridge includes a casing, a developer-carrying member, a supply member, a developing electrode, a supply electrode, and an insulating member. The casing is configured to accommodate therein developer. The developer-carrying member is configured to rotate about a rotational axis and carry the developer thereon. The supply member is configured to supply the developer to the developer-carrying member. The developing electrode is configured to be electrically connected to the developer-carrying member. The supply electrode is configured to be electrically connected to the supply member. The insulating member insulates the developing electrode and the supply electrode with each other. The developing electrode, the insulating member, and the supply electrode are overlapped in this order in an axial direction of the rotational axis.

Abstract: A cartridge includes: a first cartridge; a second cartridge; and a protection cover. The first cartridge includes: a photosensitive body; a photosensitive-body accommodating portion for accommodating the photosensitive body; and a cartridge mounting portion. The second cartridge is detachably mounted in the first cartridge and includes a developer carrier. The protection cover provides an attached state to be attached to the second cartridge and a detached state to be detached from the second cartridge. The protection cover at the attached state faces the developer carrier to protect the developer carrier. The second cartridge provides an accommodated position to be accommodated in the cartridge mounting portion when the protection cover is at the attached state, and a mounted position to be mounted in the cartridge mounting portion when the protection cover is at the detached state.
