摘要： An apparatus for fusing images to a sheet. A fuser device is provided using a transparent fusing roll having an internal heating device which focuses the energy to a narrow area of the roll adjacent the nip formed with a pressure roll. A transparent fuser roll is used in a pressure nip fusing system to take advantage of the quick response of a focused lamp system while at the same time yielding the desirable image quality attributes of the pressure nip in two roll fusing. The focused lamp is completely enclosed and the heated region of the paper is within the nip contact region so there exists no possibility of igniting the paper. A lateral temperature smoothing device, or leveling roll, is also provided to maintain a fairly uniform temperature axially across the fuser roll. This is particularly useful for a wide fuser roll, i.e., 17 inches, through which narrower paper, i.e., 11 or 14 inches, is passing to prevent the ends of the fuser roll which do not contact the paper from overheating. A quick start up from cold start is possible so that no standby power is required.
摘要翻译：用于将图像融合到片材的装置。使用具有内部加热装置的透明定影辊来提供定影装置，所述内部加热装置将能量聚焦到邻近形成有压力辊的辊隙的辊的窄区域。在压力压合系统中使用透明的定影辊以利用聚焦灯系统的快速响应，同时在两辊定影中产生压力压区的期望图像质量属性。聚焦灯完全封闭，纸张的加热区域在压区接触区域内，因此不存在点燃纸张的可能性。还提供横向温度平滑装置或流平辊以在定影辊上轴向保持相当均匀的温度。这对于较宽的定影辊（即17英寸）特别有用，较窄的纸张即11或14英寸通过该定影辊，以防止定影辊的不接触纸张的端部过热。从冷启动快速启动是可能的，因此不需要待机电源。

摘要： An apparatus for applying an electrical charge to a charge retentive surface by transporting ions through an ionically conductive liquid and transferring the ions to the member to be charged across the liquid/charge retentive surface interface. The ionically conductive liquid is contacted with the charge retentive surface for depositing ions onto the charge retentive surface via a wetted donor blade supported within a mechanically sealable housing adapted to permit movement of the wetted donor blade from an operative position in contact with the charge retentive surface, to a nonoperative position stored within the housing to prevent loss of the ionically conductive liquid in its liquid or vapor form so as to extend the functional life of the apparatus. In one specific embodiment, a wiper blade may be provided for removing any liquid droplets from the surface of the photoreceptor as may have been transferred at the donor blade/charge retentive surface interface.

摘要： A device for applying an electrical charge to a charge retentive surface by transporting ions in a fluid media and transferring the ions to the member to be charged across the fluid media/charge retentive surface interface. The fluid media is positioned in contact with a charge retentive surface for depositing ions onto the charge retentive surface. In one specific embodiment, the fluid media is a ferrofluid material wherein a magnet is utilized to control the position of the fluid media, which, in turn, can be utilized to selectively control the activation of the charging process.

摘要： An apparatus and method that insures an even distribution of liquid in an aquatron charging device across the entire length of the device. This enables uniform charging across the width of the photoreceptor. The present invention fills and pressurizes a porous tube with a liquid. The liquid evenly exudes from the pores along the entire length of the porous tube. A hydrophilic liquid retentive foam which contacts the photoreceptor surface is wrapped snugly around the tube. The conductivity and overall rate of dispensation of liquid is controlled by the pressure differential across the porous tube.

摘要： This invention relates to a process for rapidly charging uncharged toner particles to a positive polarity, which comprises adding uncharged toner particles to a positively charged developer composition comprising carrier particles and toner particles, the charged and uncharged toner particles containing conductive particles or conductive patches on their surface, which conductive patches are of a higher positive triboelectric charge than the toner polymer, contacting the charged toner particles with the uncharged toner particles causing positive charges to be transferred from the conductive particles on the charged toner particles, to conductive particles on the uncharged toner particles, within a period of from about 5 seconds to about 2 minutes, thereby resulting in substantially the same level of positive charge intensity for both the original charged toner particles and the added toner particles, such charge intensity ranging from about 5 microcoulombs per gram to about 50 microcoulombs per gram.
