Methods and devices for electrophotographic printing |
摘要 |
A printing device includes a developer for developing a latent image with toner particles; an imaging plate comprising a plurality of pixel plates; and a plurality of voltage generators connected respectively to the pixel plates. The voltage generators positively bias selected pixel plates to form a latent image that is developed with toner from the developer. Another printing device includes a developer for developing a latent image with toner particles; an imaging plate comprising a plurality of pixel plates for selectively receiving toner particles from the developer; a plurality of voltage generators for biasing respective to pixel plates; and a background grid in the imaging plate for preventing toner particles from being deposited in areas between the pixel plates, wherein the background grid is connected to a voltage generator for applying a range of biases, positive and negative to the background grid. A method of electrophotographic printing in which toner particles are moved electrostatically from a developer to develop a latent image includes positively biasing selected pixel plates of a plurality of pixel plates of an imaging plate to form the latent image; and developing the latent image with the toner particles from the developer.
