摘要： A printing apparatus has a cartridge attachment section including a terminal block having apparatus-side terminals disposed on its inclined surface, and a printing material supply pipe. Among the apparatus-side terminals, one apparatus-side ground terminal located on their center in Y direction is protruded to a greater height than the other plural apparatus-side terminals. A printing material cartridge has a circuit board, a printing material supply port, and a board mount portion that is inclined at an acute angle relative to a plane extended from an opening face of the printing material supply port. The circuit board is arranged such that one cartridge-side terminal on the circuit board comes into contact with the apparatus-side ground terminal prior to the other cartridge-side terminals in the process of attachment of the printing material cartridge to the cartridge attachment section. This arrangement enables the printing material cartridge to be attached in an adequate correct orientation or alignment to the printing apparatus. This arrangement also reduces the possibility of failure caused by application of a high voltage to the circuitry of the printing material cartridge.

摘要： A membrane valve having a membrane portion is used. The membrane valve can be formed using an elastomer. Also, the membrane valve can include N (N is an integer of 2 or greater) engaging portions that engage with the membrane support portion. Also, the membrane portion can also be affixed at a position closer to the first seal surface than the second seal surface in the seal portion. Here, the contact area of the first seal surface and the first member can be larger than the contact surface of the second seal surface and the second member. Also, in a first case where the end of the projecting portion is faced to a first plane and the membrane valve placed on the first plane, the end of the first support portion contacts the first plane and supports the membrane valve, and the end of the projecting portion can contact the first plane in a state with the membrane portion not deformed. Also, the projecting portion inserted inside the end of the coil spring can be arranged at the center axis side separated from the range of the position in which the projecting portion can contact the end of the coil spring by motion of the coil spring within the concave portion in the direction perpendicular to the center axis of the coil spring.

摘要： A charging roller is provided. The charging roller is configured to face an image carrier at a predetermined charging gap and charge the image carrier in a non-contact state. A conductive shaft is provided with a pair of annular concave portions formed on an outer circumferential surface at both ends thereof. A conductive layer is formed on the outer circumference surface at a center portion of the conductive shaft defined between the pair of concave portions. An insulating layer is formed on the outer circumferential surface at outer portions of the conductive shaft from the pair of annular concave portions. A depth of the concave portions is larger than a thickness of the conductive layer.
