摘要： An article used to seal the interface between the developer roll, doctor blade and developer housing in a laser printer toner cartridge is described. The sealing member described in the present application performs static sealing between the components while the cartridge is idle and performs dynamic sealing while the toner cartridge is used for printing, keeping the sealing surfaces free from toner by actively pushing the toner back into the developer sump. The seal has a rotary seal portion which seals between the frame of the cartridge and the developer roll, and a blade seal portion which seals between the frame of the cartridge and the doctor blade. The rotary seal portion is biased toward the surface of the developer roll and incorporates, on its face adjacent to the developer roll, ridges which act to push the toner away from the edge of the developer roll in use. The blade seal portion is biased toward the doctor blade.

摘要： A supply cartridge including a photosensitive drum, a charge roller, a developer roller, and a supply of toner, is inserted into a conventional electrophotographic (EP) machine in operative association with the gear train for such machine. One end of a shaft passing through one end cap of the photosensitive drum is inserted into a receptacle in the EP machine. The free end of a drive transmitting member on the opposite end of the drum engages the drive train, and is driven by the gear train. The drive transmitting member is an integral part of a molded end cap inserted into the open end of the photosensitive drum. The drive transmitting member may assume diverse forms. The upper surface of the drive transmitting member may be triangular in shape, while the base may be circular or triangular; tapered sidewalls extend between the upper surface and the base, and the area of the upper surface exceeds the area of the base to maximize contact with the drive train. The drive transmitting member may assume the form of three, or more, spaced fingers, which approximate the apices of a triangle. The upper surface and the base of the drive transmitting member are in straight line alignment to facilitate molding procedures while maintaining tight tolerances.

摘要： An end seal for use in an electrophotographic image forming apparatus uses an array of ridges (or grooves) to urge toner inwardly so as to help prevent toner escape. The end seal works in conjunction with a cleaning blade. The end seal includes a blade pocket for mating with the end portions of the cleaning blade and a middle portion having an array of ridges thereon. The ridges are angled inward to urge any toner trapped therebetween inward away from the end seals, where the toner can be directed to a waste reservoir in a normal fashion. This “snowplowing” action of the ridges helps prevent outward migration of toner, thereby minimizing toner escape. The end seal may be composed of two or more layers of differing materials. There may be an end seal at each end of the cleaner blade.

摘要： A waste toner removal system for an image forming device. The invention includes a mechanism for removing the waste toner from the cartridge and transporting it through a toner chute to a waste toner tank. One or more actuators within the device allow for the connection between the various elements to seal the waste toner path and prevent toner leakage. Methods of moving waste toner are also disclosed that include moving the waste toner through the cartridge and into a waste toner chute. The waste toner is moved through the chute and into a waste toner tank where it may be removed from the device.

摘要： An image forming apparatus includes a waste toner system that collects waste toner in a waste toner container. An amount of waste toner collected in the container is increased by using a motor-driven toner distributing member that distributes accumulated toner within the container. The waste toner system may detect the accumulation of waste toner by monitoring a motor control circuit while the toner distributing member is being driven. For example, the system may detect excess accumulation by comparing the monitored values of a speed control signal with one or more reference values corresponding to nominal accumulation conditions. Whether or not the motor is speed controlled, the apparatus may use a shared motor that drives one or more image forming process members and the toner distributing member. A drive arrangement may be used to selectively drive the toner distributing member based on motor direction to avoid interfering with image forming operations.
