摘要： An apparatus and method develops an electrostatic latent image directly from an imaging member to a final substrate, such as paper or the like. An image development apparatus and method creates a first electrostatic latent image on an imaging member and deposits a toner layer on the imaging member. The image developer then generates a second electrostatic latent image in the toner layer in response to the first electrostatic latent image on the imaging member. The second electrostatic latent image can be generated by either a broad source ion charging device or an air breakdown charging device. Next, the latent image bearing toner layer is selectively separated and developed such that the image areas are developed directly from the imaging member onto a final substrate and the non-image areas remain on the imaging member.

摘要： A novel image development method and apparatus are disclosed, whereby image-wise charging of a toner layer is accomplished by induce air breakdown electrical discharge such that free mobile ions are introduced in the vicinity of an electrostatic latent image coated with a layer of developing material. The latent image causes the free mobile ions to flow in an image-wise ion stream corresponding to the latent image, which, in turn, leads to image-wise charging of the toner layer, such that the toner layer itself becomes the latent image carrier. The latent image carrying toner layer is subsequently developed and transferred to a copy substrate to produce an output document.
