    • Disclosed is a liquid developer comprising a colorant and a substantial amount of a curable liquid vehicle having a viscosity of no more than about 500 centipoise and a resistivity of no less than about 10⁸ ohm-cm. One embodiment of the invention is an electrophoretic liquid developer comprising a substantial amount of a curable liquid vehicle having a viscosity of no more than about 20 centipoise and a resistivity of no less than about 5 × 10⁹ ohm-cm, a charge control agent, and colored particles capable of becoming charged and migrating through the liquid vehicle to develop an electrostatic latent image. Another embodiment of the invention is a polarizable liquid developer comprising a colorant and a substantial amount of a curable liquid vehicle having a viscosity of from about 25 to about 500 centipoise and a resistivity of from about 10⁸ to about 10¹¹ ohm-cm. Yet another embodiment of the invention is a photoelectrophoretic liquid developer comprising a substantial amount of a curable liquid vehicle having a viscosity of no more than about 20 centipoise and a resistivity of no less than about 5 × 10⁹ ohm-cm and photosensitive colored particles.

    • A process for treating a seamed flexible electrostatographic imaging belt including providing an imaging belt including at least one imaging layer including a thermoplastic polymer matrix and a seam extending from one edge of the belt to the other, the seam having a region on the belt adjacent each side of the seam and also having an exposed surface on each side of the belt, supporting the belt with at least one vacuum holding device spaced from the seam while maintaining the seam and region of the belt adjacent each side of the seam in an arcuate shape having at least a substantially semicircular cross section having a radius of curvature of between about 9.5 millimeters and about 50 millimeters, heating the thermoplastic polymer matrix of the imaging layer in the seam and the region of the belt adjacent each side of the seam to at least the glass transition temperature (Tg) of the thermoplastic polymer matrix without significantly heating the support member, and contacting the exposed surface of the seam and regions on each side of the belt with a gas to rapidly cool the seam and regions on each side of the belt to a temperature below the glass transition temperature of the polymer matrix while maintaining the arcuate shape of the region of the belt adjacent each side of the seam. Apparatus for carrying out this process is also disclosed.
    • 一种用于处理缝合的柔性静电摄影成像带的方法,包括提供包括至少一个包含热塑性聚合物基体的成像层和从所述带的一个边缘延伸到另一个边缘的接缝的成像带,所述接缝具有在每个所述带上的带上的区域 并且还具有在带的每一侧上的暴露表面,用至少一个与接缝隔开的真空保持装置支撑带,同时将接缝和接缝的每个侧面的区域保持为弓形形状 具有至少具有约9.5毫米至约50毫米的曲率半径的基本上半圆形的横截面,将接缝中的成像层的热塑性聚合物基体和邻近接缝的每一侧的带的区域加热至少 热塑性聚合物基体的玻璃化转变温度(Tg),而不显着加热支撑构件,并使暴露部分接触 d表面和具有气体的带的每一侧上的区域,以快速地将接缝和带的每一侧的区域冷却到低于聚合物基体的玻璃化转变温度的温度,同时保持该区域的弧形形状 该皮带邻近接缝的每一侧。 还公开了用于执行该过程的装置。
