Abstract: In a xerographic development apparatus using a magnetic brush formed from magnetic carrier particles, a magnetic strip disposed downstream of the development zone along the direction of motion of the photoreceptor retains a separate, small brush of carrier particles near the photoreceptor. The brush acts as a barrier separating a flow of nulldirtynull air (laden with airborne toner particles) upstream of the strip, and a flow of clean air downstream of the strip.

Abstract: A printing apparatus includes a guide member for directing sheets toward a transfer zone. The guide member defines a set of ribs which hold the sheets above the main surface of the guide member. Thus, any stray marking material which lands on the guide member is relatively unlikely to contact a sheet moving over the guide member.

Abstract translation: 打印装置包括用于将纸张朝向转印区域引导的引导构件。 引导构件限定了将片材保持在引导构件的主表面上方的一组肋。 因此，落在引导构件上的任何杂散标记材料相对不太可能接触在引导构件上移动的片材。

Abstract: A magnetic roll, such as for use in a xerographic printing apparatus, is formed from two semicylindrical partial cylinders. The partial cylinders can be molded and attached to each other to form a complete cylinder defining magnetic poles along the circumference thereof.
