Abstract

A jump monocomponent development arrangement includes a dielectric photoreceptor belt having an image-bearing surface on one side and a conductive surface on the other side with a thickness in the range from 30 microns to 50 microns and an electrostatic charge image on the image-bearing surface has a contrast potential of 1000 to 2000 volts. Toner particles with an average diameter in the range from one micron to 20 microns are transferred from a developer roll to the electrostatic charge image using a bias potential in the range from 500 volts to 1500 volts across a development gap in the range from 100 microns to 500 microns. The difference between the maximum development voltage and the threshold development voltage is less than the contrast potential.

Dependent claims

A jump monocomponent development arrangement comprising:

a dielectric photoreceptor member having an image-receiving surface on one side to convey an electrostatic charge image adjacent to a development station and having a conductive surface on the opposite side;
a development station including a developer roller having a toner-carrying surface separated by a development gap from the image-receiving surface of the photoreceptor member to apply toner particles to an electrostatic charge image thereon by jump development;
and
a potential source providing a bias potential between the developer roller and the conductive surface of the photoreceptor member;
wherein the thickness of the dielectric photoreceptor member is selected to provide a contrast potential which is greater than the voltage width of the electrostatic charge image on the image-receiving surface of the photoreceptor member during development.
