摘要： An apparatus for cleaning a charge retentive surface of a photoreceptor which includes a cleaning blade for removing debris from the charge retentive surface of a photoreceptor. In the environment of a xerographic copier and/or printer, corona effluents are emitted by the high voltage charging devices. These effluents, which are strong oxidizing agents, may be adsorbed by or otherwise attach a cleaning blade polymer matrix. Thereafter, such corona species outgassing from a blade may chemically and/or otherwise attack the photoreceptor during prolonged blade/photoreceptor contact, resulting in print/copy defects, as well as permanent damage to the photoreceptor and/or cleaning blade. The present invention relates to impregnating or otherwise treating the cleaning blade with an antioxidant such that its presence in the blade polymer matrix can prevent corona species penetration or accumulation by chemically neutralizing and destroying the species upon exposure. In one example, the cleaning blade is impregnated with an antioxidant such as 1,3-Diphenylisobenzofuran. Such preventive measures to hinder or eliminate the corona species absorption and accumulation in the cleaning blade polymer matrix can, in principle, be employed to resolve the corona species outgassing problem.
摘要翻译：一种用于清洁感光体的电荷保持表面的设备，其包括用于从感光体的电荷保持性表面去除碎屑的清洁刮板。在静电复印机和/或打印机的环境中，电晕放电由高压充电装置发射。作为强氧化剂的这些流出物可被吸附或以其他方式附着清洁刮刀聚合物基质。此后，从刀片脱气的这种电晕物质可以在延长的刀片/感光器接触期间化学地和/或以其他方式攻击感光体，导致印刷/复印缺陷，以及对感光体和/或清洁刮片的永久性损伤。本发明涉及用抗氧化剂浸渍或以其他方式处理清洁刮板，使得其在叶片聚合物基质中的存在可以通过在暴露时化学中和和破坏物种来防止电晕物质的渗透或积聚。在一个实例中，清洁刮板用抗氧化剂如1,3-二苯基异苯并呋喃浸渍。原则上，用于阻止或消除清洁刮刀聚合物基体中的电晕物质吸收和积聚的这种预防措施可用于解决电晕物质除气问题。

摘要： An image forming apparatus includes a main frame, a plurality of process cartridges, a cartridge-supporting body, a belt, a waste toner cartridge, a contact-separation mechanism, and a collective conveying unit. Each process cartridge includes a photosensitive drum and a drum cleaning unit collecting waste toner on the drum. The cartridge-supporting body is movable between an internal position inside the frame and an external position outside the frame. The belt confronts the process cartridges in the internal position. The waste toner cartridge accommodates the waste toner collected from the drums. The contact-separation mechanism moves the cartridge-supporting body between a contact position where the drums are in contact with the belt and a separated position where the drums are out of contact with the belt. The collective conveying unit aggregates waste toner collected from drums and conveys collectively the aggregated waste toner to the waste toner cartridge.

摘要： An image forming apparatus includes a main frame, a plurality of process cartridges, a cartridge-supporting body, a belt, a belt cleaning unit, a waste toner cartridge, and a collective conveying unit. Each drum-cleaning unit collects waste toner on a corresponding photosensitive drum. The cartridge-supporting body supports the process cartridges and is movable between an internal position inside the main frame and an external position outside of the main frame. The belt cleaning unit collects waste toner on the belt. The waste toner cartridge accommodates both waste toner collected from the photosensitive drums by the drum-cleaning units and waste toner collected from the belt by the belt cleaning unit. The collective conveying unit aggregates both waste toner collected from the photosensitive drums by the drum-cleaning units and waste toner collected from the belt by the belt cleaning unit and conveys the aggregated waste toner to the waste toner cartridge.
