    Abstract: A cartridge unit includes: a first unit which includes a first supporting portion and a second supporting portion; and a second unit which includes a first supported portion, a second supported portion, and a storage member, the storage member including a memory contact, and a contact arrangement surface on which the memory contact is disposed. The second unit rotates from a first position to a second position in a state in which the first supported portion is supported by the first supporting portion and the second supported portion is supported by the second supporting portion to be positioned with respect to the first unit. A normal direction of the contact arrangement surface faces toward a direction in which the memory contact is exposed. The normal direction faces toward a direction opposite to a direction in which the second unit is directed from the first position to the second position.

    Abstract: A developing cartridge includes: a housing accommodating developing agent; a developing roller including a developing-roller shaft extending in a first direction; an electrode made of an electrically conductive resin; and a first collar made of an electrically non-conductive resin. The electrode is positioned at one end portion of the housing in the first direction. The electrode is electrically connected to the developing-roller shaft. The first collar covers one end portion of the developing-roller shaft in the first direction. The first collar includes: a first arm extending in the first direction; and a first pawl configured to engage with the electrode. The first pawl protrudes from the first arm in a direction away from the developing-roller shaft. The first pawl is movable between: a first position at which the first pawl is in engagement with the electrode; and a second position at which the first pawl is separated from the electrode.

    Abstract: The present disclosure provides a voltage conversion apparatus, an image-forming assembly, a process cartridge and a process cartridge group. The voltage conversion apparatus is applied to a process cartridge. The process cartridge includes a first image-forming member and a second image-forming member. The voltage conversion apparatus includes a voltage conversion module, where an input terminal of the voltage conversion module is configured to be electrically connected to the first image-forming member, and an output terminal of the voltage conversion module is configured to be electrically connected to the second image-forming member; and the voltage conversion module is configured to convert a first voltage received by the first image-forming member into a second voltage. The first voltage is a voltage required for the first image-forming member to operate, and the second voltage is a voltage required for the second image-forming member to operate.

    Abstract: The present disclosure provides a process cartridge and a potential detection part. The process cartridge includes a cartridge body, a photosensitive drum rotatably installed at the cartridge body, and a potential detection part configured to detect an electrical signal on the image-forming region. The potential detection part includes a detection starting portion and a detection ending portion; the detection starting portion and the detection ending portion respectively correspond to a detection starting position and a detection ending position of a detectable region of the potential detection part along a first direction; a maximum distance along the first direction between orthographic projections of the detection starting portion and the detection ending portion on the image-forming region is L1; a length of the image-forming region along the first direction is L2; the first direction is in parallel with an axis direction of the photosensitive drum; and L1/L2>⅓.
