Abstract: This is an electrophotographic process comprising the step of contacting a latent electrostatic image with a developer comprising carrier and toner. The carrier is a core coated with a continuous film of a fluoropolymer and a modifying resin. This carrier has a positive triboelectric charge with respect to the toner. This positive charge is obtained by curing the coated carrier at a temperature less than 700*F.

Abstract translation: 这是一种电子照相方法，其包括将静电潜像与包含载体和调色剂的显影剂接触的步骤。 载体是涂覆有含氟聚合物和改性树脂的连续膜的芯。 该载体相对于调色剂具有正的摩擦电荷。 这种正电荷是通过在低于700°F的温度下固化涂覆的载体而获得的。
