    • Disclosed is a process for forming images which comprises (a) generating an electrostatic latent image; (b) contacting the latent image with a developer comprising a colorant and a substantial amount of a vehicle with a melting point of at least about 25° C., said developer having a melting point of at least about 25° C., said contact occurring while the developer is maintained at a temperature at or above its melting point, said developer having a viscosity of no more than about 500 centipoise and a resistivity of no less than about 108 ohm-cm at the temperature maintained while the developer is in contact with the latent image; and (c) cooling the developed image to a temperature below its melting point subsequent to development. Specific processes disclosed include electrophoretic development processes, polarizable liquid development processes, and photoelectrophoretic development processes. Optionally, the developed image is transferred to a substrate subsequent to development.
    • 公开了一种用于形成图像的方法,其包括(a)产生静电潜像; (b)使潜像与包含着色剂和大体积的至少约25℃熔点的载体的显影剂接触,所述显影剂具有至少约25℃的熔点,所述接触 当显影剂保持在等于或高于其熔点的温度时,所述显影剂在显影剂接触时保持的温度下具有不超过约500厘泊的粘度和不小于约108欧姆 - 厘米的电阻率 与潜像; 和(c)在显影后将显影图像冷却至低于其熔点的温度。 所公开的具体方法包括电泳显影方法,可极化液体显影方法和光电泳显影方法。 任选地,显影的图像在显影之后转移到基底。
