Abstract: A roller for pneumatically supporting copy sheets in the transfer station of a xerographic machine. The roller is electrically biased to transfer toner images from a photoreceptive member to copy sheets supported on the roller. Recirculation of the roller may effect the transfer of superimposed images to the backing sheets.

Abstract: An apparatus for developing a latent electrostatic image with developer material wherein development is effected by utilizing a rotating magnetic brush mechanism. The axis of rotation of the magnetic brush extends in a skewed relationship with respect to the axis of rotation of the image bearing surface. The developer material attracted to the magnetic brush is doctored to form a concave outer surface of developer on the member for effective development of the latent image without streaking. Alternatively, the magnetic member carrying developer possesses a concave-like exterior surface to transport developer into uniform stroking contact with the image bearing surface similarly to prevent streaking defects in the developed image. Similarly the magnetic field of the brush may be shaped so as to be weakest in the middle of the brush creating, automatically, a concave shaped surface of developer.

Abstract translation: 一种用显影剂材料显影静电潜像的装置，其中通过利用旋转磁刷机构进行显影。 磁刷的旋转轴线相对于图像承载表面的旋转轴线呈倾斜关系延伸。 吸引到磁刷的显影剂材料被设计成在构件上形成显影剂的凹形外表面，以有效地显影潜像而不产生条纹。 或者，携带有磁性构件的显影剂具有凹形的外表面，以将显影剂输送到与图像承载表面均匀的触摸接触，以防止显影图像中的条纹缺陷。 类似地，刷子的磁场可以被成形为在刷子的中间最弱，从而自动地形成显影剂的凹形表面。
