摘要： Controlling the charge on toner in a development station of an electrographic reproduction apparatus, wherein data relative to latent image charge carrying member voltage and image density control patches are sensed and development potential to achieve an aim density is calculated therefrom. A delta from an optimum development potential range is calculated, and in response to the determined delta, an amount of liquid charge control agent, from a supply of suitable liquid charge control agent, necessary to be added to the developer material in the development station to bring the toner to substantially a charge level that will enable a desired optimum developer potential is calculated. The calculated amount of liquid charge control agent is then injected directly into the development station.

摘要： A method of producing a custom color particulate toner for use in a two-component developer by mixing two or more component color toners. The component color toners are each surface treated with a blend of two or more types of silica particles, which differ in the functional groups appended to them. The silica blend for each component color toner is chosen so that, when the component color toners are mixed together to form the custom color mixture, they will all tribocharge to the same charge-to-mass ratio when mixed with a carrier to form a developer.

摘要： An electrostatic image on an image member already containing a loose dry first toner image is toned with a second toner, for example, a toner of a second and different color from the first toner image. The toning is accomplished by a developer having a high coercivity permanently magnetized carrier and toner which is moved through a development zone by a rapidly rotating core inside a sleeve on which the developer moves. Pole transitions caused by the rapidly moving core make the high coercivity permanently magnetized carrier move vigorously in a wave motion having alternating crests and troughs. Scavenging of the first toner image is prevented by separating the sleeve from the image member sufficiently that the crests of the developer do not touch the image member during the toning process. An alternating electrical field is applied between the sleeve and the image member to enhance development.
