    • This specification discloses a method of toner transfer development in which a low frequency alternating electrical bias is applied to the space between a latent image bearing member and a developer carrying member to develop the latent image on the latent image bearing member, and an apparatus for carrying out the same method. This bias has a first stage in which one-sided movement of developer particles from the developer carrying member to the image area of the latent image bearing member may take place, a second stage in which reciprocal movement of developer particles is effected between both the image and non-image areas of the latent image bearing member and the developer carrying member, and a third stage in which the intensity of the bias is reduced so that one-sided movement of developer particles from the developer carrying member to the image area and one-sided movement of developer particles from the non-image area to the developer carrying member may take place.
    • 本说明书公开了一种调色剂转印显影方法,其中将低频交替电偏压施加到潜像承载部件和显影剂承载部件之间的空间以使潜像承载部件上的潜像显影,以及用于承载 出来一样的方法。 该偏压具有第一阶段,其中可能发生显影剂颗粒从显影剂承载构件到潜像承载构件的图像区域的单面运动,第二阶段是在两个图像之间实现显影剂颗粒的往复运动 和潜像承载部件和显影剂承载部件的非图像区域,以及第三阶段,其中偏压的强度减小,使得显影剂颗粒从显影剂承载部件的单面移动到图像区域和一个 显影剂颗粒从非图像区域移动到显影剂承载构件可能发生。
