摘要： A backup roller is formed by a member having a rotational axis and a circumferential region around which a plurality of teeth are arranged. Each tooth of the plurality of teeth has a tip end extending in a direction away from the rotational axis. When the backup roller is rotated the tip end of each of the plurality of teeth sequentially extends toward the rotational axis of a drive roller at an angle non-orthogonal to the rotational axis of the drive roller.
摘要翻译：支撑辊由具有旋转轴线和围绕多个齿排列的周向区域的构件形成。多个齿的每个齿具有沿远离旋转轴线的方向延伸的尖端。当支撑辊旋转时，多个齿中的每一个的尖端依次以与驱动辊的旋转轴线正交的角度朝向驱动辊的旋转轴线延伸。

摘要： Methods and apparatus for increasing the bias force between a developer half and a cleaner half of a process cartridge are disclosed. One or more springs are interposed between the cleaner half and the developer half of the process cartridge. These springs are of sufficient strength to maintain a constant separation between the developer and the photosensitive member of the process cartridge. Sources of force other than springs, such as weights or elastic members may also be employed to provide and increase the bias force urging the developer and photosensitive member together.
摘要翻译：公开了用于增加处理盒的显影剂半部和清洁器一半之间的偏压力的方法和装置。清洁器一半和处理盒的显影剂一半之间插入一个或多个弹簧。这些弹簧具有足够的强度以保持显影剂和处理盒的感光构件之间的恒定间隔。还可以使用诸如重物或弹性构件的弹簧之外的力源来提供并增加将显影剂和感光构件一起推动的偏压力。

摘要： A print media feed system for advancing a sheet of print media having a leading edge and a trailing edge in a sheet feed direction through a print zone in an imaging apparatus includes a rotating support positioned downstream of an exit roller in relation to a sheet feed direction. The rotating support provides a rotating support surface that engages a non-printed side of the sheet of print media downstream of the exit roller while the trailing edge of the sheet of print media is advanced through the print zone by the exit roller, the rotating support not contributing to advance the trailing edge of the sheet of print media through the print zone, but contributing to advance the sheet of print media after the sheet of print media is released by the exit roller.
摘要翻译：一种打印介质供给系统，用于使成像装置中的打印区域沿片材进给方向推进具有前缘和后缘的打印介质片，包括位于出纸辊相对于送纸方向。旋转支撑件提供旋转的支撑表面，该支撑表面在出纸辊的下游与打印介质片的非印刷侧接合，同时打印介质片的后缘通过出纸辊前进穿过打印区域，旋转支撑件没有促进通过打印区域打印介质片的后缘，但是有助于在出纸辊释放一页打印介质之后推进该打印介质片。
