Abstract
Embodiments pertain to a novel imaging member, namely, an electrostatic latent image generating member, and methods for using the same, that can generate an electrostatic latent image digitally with fewer steps and without using a raster output scanner (ROS) or free charge carriers. Embodiments provide a novel way of generating an electrostatic latent image without the shortfalls suffered by current photoreceptors, such as for example, charge mobility issues, unstable cycling, surface wear, lateral charge migration and sensitivity to light shock.
Claims19
A method for creating an electrostatic latent image, comprising:
- providing an electrostatic imaging member, further comprising
- a support substrate having individually addressable pixel pads arranged on or in the support substrate, and
- a dielectric layer disposed over the individually addressable pixel pads;
- applying an electrostatic charger to the electrostatic imaging member;
- and
- generating an electrostatic image, wherein the electrostatic image is generated in a single step by grounding selected pixel pads in a pattern that is to be printed while applying the electrostatic charger to the surface of the dielectric layer of the electrostatic imaging member and further wherein each pixel pad of the array of pixel pads has a width of 10 um and a separation distance of 10 um.
An electrostatic imaging device, comprising:
- an electrostatic imaging member comprising
- a support substrate having individually addressable pixel pads arranged on or in the support substrate, and
- a dielectric layer disposed over the individually addressable pixel pads, wherein the individually addressable pixel pads are patterned on the support substrate in an array and further wherein each pixel pad of the array of pixel pads has a width of 10 um and a separation distance of 10 um;
- and
- an electrostatic charging device, wherein an electrostatic image is generated by grounding selected pixel pads in a pattern that is to be printed while applying the electrostatic charger to the surface of the dielectric layer of the electrostatic imaging member.
An image forming apparatus for forming images on a recording medium comprising:
