Abstract: A device comprising a heating, and fixing roller and a pressing roller, the heating and fixing roller having a peripheral surface to which powder of a powder image formed on a recording sheet by a xerographic method is hard to adhere and the pressing roller having a peripheral surface to which the powder readily adheres. The recording sheet is passed between the two rollers so that the powder image on the recording sheet may be fixed.

Abstract: A device provided with a developing roller formed on its periphery with a multitude of valleys and valley, with the crests serving as fluid containing sections which are supplied with a developing fluid. The device is also provided with a doctor member made of a resilient, fluid absorbing material and adapted to adjust the level of the fluid contained in each fluid containing section such that the fluid is maintained at a level below the crests, or the maximum diameter portions of the developing roller. A recording sheet on which an electrostatic image is formed is brought into contact with the developing roller so that the fluid contained in the fluid containing sections selectively adheres to the electrostatic image to render the image visible. The visible images produced by this method may vary in density depending on the quantities of electricity carried by the charged regions of the electrostatic images.

Abstract translation: 具有在其周边上形成有多个谷和谷的显影辊的装置，其中波峰用作流体容纳部分，供给显影液。 该装置还设置有由弹性流体吸收材料制成的刮刀构件，并且适于调节包含在每个流体容纳部分中的流体的水平，使得流体保持在低于波峰的水平或​​最大直径部分 的显影辊。 其上形成有静电图像的记录纸与显影辊接触，使得包含在流体容纳部分中的流体选择性地粘附到静电图像以使图像可见。 通过该方法产生的可见图像的密度可以根据静电图像的带电区域携带的电量而变化。
