    摘要： A DEVELOPER FOR DEVELOPING ELECTROSTATIC IMAGES ON SURFACES. THE DEVELOPER CONTAINS AT LEAST TWO TYPES OF PARTICLES, ONE OF WHICH IS AN INSULATOR AND IS PREFERABLY OF FINER SIZE AND THE OTHER OF WHICH IS A MORE CONDUCTIVE PARTICULATE DEVELOPER AND PREFERABLY OF COARSER SIZE WITH POSSIBLY A FURTHER PARTICULATE MATERIAL WHICH HAS ONE END INSULATING AND THE OTHER RELATIVELY MORE CONDUCTIVE OR POLAR WHEREBY THE MORE CONDUCTIVE PARTICLES TEND TO DEVELOP THE EDGES OF THE IMAGE AND THE INSULATING PARTICLES THE INTERMEDIATE PORTIONS BETWEEN THE EDGES BUT WHEREIN THE INSULATOR PARTICLES ENABLE THE RELATIVELY MORE CONDUCTIVE PARTICLES TO BE RETAINED ON A SURFACE BY A LIMITING CHARGE TRANSFER OF THE RELATIVELY MORE CONDUCTIVE PARTICLES TO THE SURFACE CONTAINING THE THE ELECTROSTATIC IMAGE, AND THE THIRD TYPE OF PARTICLE CAN ROTATE AS A STIRRER.

    摘要： A method of developing electrostatic images comprising subjecting a surface containing an electrical image to a liquid developer having two dissimilar components, one of which is a first developer component having a polarity such that it develops the image by attracting the first developer component to the image. A bias field is maintained through the liquid such that as the image is developed by the first developer component the second developer component is moved away from the surface being developed. When the first developer has been differentially developed on the surface the polarity of the bias field is reversed to cause the second developer component to be deposited on the first developer component.

    摘要： An improved developer for xerographic surfaces in which an image is produced without an applied charge, in which a controlled developer pigment of one polarity is suspended in an insulating carrier liquid, and a second developer medium also capable of acting as a developer, but of opposite polarity and incapable of wetting the first pigment, is used to enhance deposition of the first pigment in image areas and to shield the non-image areas against deposition of the first developer.

    摘要： The invention relates to a method of and means for transferring recorded signals and latent electrostatic images before development. The insulating medium which is placed over the photoconductor surface is so constructed that the dielectric constant or permittivity on one side is lower than the dielectric constant on the other side. This can be achieved by forming the insulating medium of a laminate of two differing materials of differing dielectric constants.
