摘要:
A method of inkjet printing includes using a grayscale inkjet print head. The inkjet print head is driven driving to eject a number of successive ink droplets from the ink chamber in accordance with print tone data provided to the grayscale print head, the number of successive ink droplets forming a multiple-droplet drop creating a printed dot of appropriate tone on the receiving medium. The method includes the step of excluding print tone data corresponding with the ejection of a single-droplet drop from being provided to the grayscale print head. A preferred embodiment includes the removal of this print tone data from the data provided to the grayscale print head. A more preferred embodiment includes applying a multilevel halftoning technique for avoiding the use of print tone data corresponding with a single-droplet drop during the generation of the print tone data for inkjet printing the image with the grayscale print head.

A photoconductive recording material described containing a support and a charge generating layer (CGL) in contiguous relationship with a charge transporting layer (CTL) containing a p-charge transporting material (p-CTM), wherein the charge generating layer (CGL) does not contain a charge transporting material but comprises a charge generating material and a binder, wherein the binder is made insoluble in methylene chloride by crosslinking and the binder which is composed essentially of one or more polyepoxy compounds self-crosslinked under the influence of an amine catalyst and/or crosslinked by reaction with at least one primary and/or secondary poly NH-group amine.
摘要:
A toner composition is provided wherein by adding aliphatic lower molecular weight compounds which are partly or completely compatible with the binder resin(s), the melt viscosity of the toner composition can be lowered while the glass transition temperature (Tg) is more or less constant. Inclusion of these adding aliphatic lower molecular weight compounds, having a number average molecular weight, as measured by GPC in toluene, of from 500 to 3,000, results in toner compositions with a better adhesion and gloss and still an acceptable level of FOT and hot-offset. Also provide is a method for fixing toner images on a substrate.
