Abstract

The present invention relates to materials and methods for direct digital marking in which surface charge contrast can be created by inversely addressing adjacent charge-injected pixels of a bipolar imaging element and can be developed with enhanced image contrast at reduced transistor voltages .

Description

technical field [0001] The present invention relates to xerographic printing and marking systems, and more particularly, to systems and methods of direct digital marking. Background technique [0002] Generally, there are two digital printing technology platforms, electrostatic and inkjet printing. Modern xerographic printing involves multiple steps: charging a photoreceptor and forming a latent image on the photoreceptor; developing the latent image; transferring the developed image to a medium and fixing it; erasing and cleaning the photoreceptor device. Although xerography is a mature technology, challenges remain in reducing unit production costs (UMC) and running costs. Unlike digital inputs, xerographic systems are basically analog devices. [0003] Solid-state inkjet printing (SIJ) is another printing technology that is now used in the color office market and is moving into the production color market. However, there are many challenges to mastering SIJ, including...
