摘要： The ink cartridge comprises a cartridge body with an ink chamber. On one side of the cartridge body is provided an ink supply port, and an air channel is positioned on the opposite side. The ink chamber is composed of a main chamber and a communicating sub-chamber, an ink-out inspection prism being provided close to the communicating portion. A check valve through which the sub-chamber is communicated with the ink supply port is provided sideways between the side walls adjacent to the ink supply port. In this invention, the nominal volume of each ink cartridge is increased, and there is no such problem that a certain amount of ink continues to be fed after the ink-out indicative signal being sent out in case of no porous material. Further, the technical solution of the sideways-provided check valve improves the manufacturability and the ink supply stability.

摘要： Disclosed is a developer cartridge. The developer cartridge comprises a cartridge box which comprises a toner compartment and a toner outlet; a stirring member which is rotationally supported inside the toner compartment; a developing roller which is rotationally supported on the toner outlet; a gear set which is installed on the exterior wall of the cartridge box which receives driving force and drives the stirring member and the developing roller; a rotation member (4) which is rotationally installed on the exterior wall of the cartridge box and is provided with a clutch gear and a coaxial cam (41) wherein the clutch gear has a small-diameter portion (43) which is clearance-fitted with one gear top of the gear set and a large-diameter portion (42) which is interference-fitted with the gear top and wherein the large-diameter portion (42) is provided with an elastic friction layer along the circumference and the cam (41) is in a staggered phase with the clutch gear; a contact member (5) which is rotationally installed on the exterior wall of the cartridge box and has a contact end (51) for contacting the cam (41) and a trigger end (52); and an elastic member (6) which is installed between the cartridge box and the contact member (5) and forces the contact end (51) to contact with the cam (41).

摘要： A process cartridge used in an image forming apparatus, the process cartridge having a photosensitive drum (6), a developer roller (5), a conductive electrode (12) and a rectifier (13). The photosensitive drum (6) and the developer roller (5) are contacted with each other. The conductive electrode (12) is contacted with a power supply electrode (14) in the image forming apparatus to receive a developing bias. The rectifier (13) converts an alternating current bias voltage into a direct current bias voltage. The rectifier (13) is electrically connected between the conductive electrode (12) and the developer roller (5). A rectifier (13) converting an alternating current bias voltage into a direct current bias voltage is added into a contact development process cartridge in the present invention. Therefore, the contact development process cartridge can be applied to a printer using a jumping development method.
