Latent electrostatic image colorizing method for use in laser printer, involves providing toner fluid, which uniformly flows over edge opposite to charge pattern, where edge forms extremely inhomogeneous electrostatic field with pattern

摘要

The method involves providing a toner fluid, which uniformly flows in small distance from an image carrier (1) over an edge opposite to a charge pattern in a tonering unit (2). Excess toner fluid is extracted into an extraction channel (10) by depression, where dimension of the extraction channel is adjustable. The extracted toner fluid is precipitated in a precipitation container (13), and is supplied to a storage container. The edge is sharp-edged to form an extremely inhomogeneous electrostatic field with the charge pattern. An independent claim is also included for a device for colorizing a latent electrostatic image with a fluid toner.
