    摘要： Electrostatic latent images are developed in a liquid electrophoretic developer, and during the development, developer immediately adjacent the image whose toner concentration has become depleted is removed from the image area and replaced by fresh developer. Images are thereby more fully developed to the extent of the electrostatic charge, eliminating edge and halo effects that result from incomplete development and the preferential attraction of toner to areas of higher electrostatic charge over adjacent areas of lower charge.

    摘要翻译： 在液体电泳显影剂中显影静电潜像，并且在显影期间，紧邻着色剂浓度已经耗尽的图像的显影剂从图像区域中去除并被新鲜的显影剂代替。 因此，图像被充分地发展到静电电荷的程度，消除了由不完全显影引起的边缘和光环效应，以及将调色剂优先吸引到较低电荷相邻区域的较高静电电荷。

    摘要： Upper and lower guides are curved in the direction of the path of movement of the copy material to be developed and extend transversely of such path for a distance greater than the width of the copy material. Opposed walls are connected with the ends of these guides to define a confined arcuate space with an inlet slot and an outlet slot. A liquid developer distribution outlet opens into such arcuate space adjacent to and inwardly of the inlet slot for distributing a flow of developer fluid in a pattern extending transversely of said path for a distance substantially the same as the width of the copy material. The liquid developer is forced through said outlet under pressure resulting in a turbulent flow of the developer liquid throughout the arcuate space thereby causing a substantial quantity of fresh, active, charged toner particles to come into contact with the latent electrostatic image on the copy material.

    摘要翻译： 上下引导件沿待显影的复制材料的移动路径的方向弯曲，并且沿着该路径横向延伸一个大于复印材料的宽度的距离。 相对的壁与这些引导件的端部连接以限定具有入口狭槽和出口狭槽的有限弧形空间。 液体显影剂分配出口通向入口槽附近和内部的这样的弧形空间，用于将显影剂流的流动分布在与所述路径横向延伸的图案中，距离基本上与复制材料的宽度相同。 液体显影剂在压力下被迫通过所述出口，导致显影液在整个弧形空间中的湍流，从而导致大量新鲜的带活动的调色剂颗粒与复印材料上的静电潜像接触。

    摘要： A development device of an electrostatic latent image wherein rotatable and cylindrical development electrodes comprising the conductive center portion which has a small radius and will face to an electrostatic latent image on a flexible electrophotographic material, and two flange portions which have a large radius respectively and will support the both ends of said material are placed such that differences between said radius of the center portion and said radius of flange portions become smaller with the proceeding of the development, thereby a print can be made with extremely small halos, streaks, fogs and edge effects.

    摘要： AN ELECTROSTATOGRAPHIC IMAGING MEMBER BEARING AN ELECTROSTATIC LATENT IMAGE ON A RECORDING SURFACE IS BROUGHT INTO CONTACT WITH A TONER LAYER ON THE SURFACE OF A DONOR MEMBER IN A LIQUID DEVELOPER BATRH, SEPARATED SLIGHTLY FROM THE DONOR MEMBER AND THEREAFTER SUBJECTED TO AN ELECTRIC FIELD WHICH CAUSES TONER PARTICLES IN THE BACKGROUND AREAS OF THE RECORDING SURFACE AS WELL AS TONER PARTICLES SUSPENDED IN THE SPACE BETWEEN THE RECORDING SURFACE AND THE DONOR MEMBER TO ELECTROPHORETICALLY MIGRATE TO THE DONOR MEMBER. THE DEVELOPED IMAGE ON THE RECORDING SURFACE PASSES THROUGH THE ZONE SUBJECTED TO THE ELECTRIC FIELD TO FURTHER CLEAN THE RECORDING SURFACE. SUBSEQUENTLY A UNIFORM LAYER OF TONER IS ELECTROPHORETICALLY DEPOSITED ON THE DONOR.

    摘要： Electrophotographic developing apparatus for applying a liquid developer to one surface of an electrophotographic recording element carrying the electrostatic image thereon so as to render the electrostatic image visible, the apparatus being adapted to apply liquid developer by a surface immersion technique and including edge control means arranged to contact portions of the recording element adjacent the side edges of the recording element as it moves past the reservoir containing the liquid developer, the edge control means preventing immersion of portions of the front surface of the recording element extending inwardly of the side edges for a predetermined distance whereby the back surface of the recording element is kept free from liquid developer.
