Electrostatic imaging member and methods for using the same

摘要

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 through charge acceptance control and without the need for conventional post charging photodischarge, eliminating process steps and avoiding limitations in system speed due to the transit time of charge carriers after light exposure.

1. An image forming apparatus for forming images on a recording medium comprising:
a) an electrostatic imaging device having a charge retentive-surface for receiving an electrostatic latent image thereon, wherein the electrostatic imaging device comprises
an electrostatic imaging member comprising
a substrate,a charge generation layer disposed on the substrate, anda charge transport layer comprising a charge transport molecule disposed on the charge generation layer, wherein electrostatic imaging member is light-sensitive;wherein the charge transport molecule is selected from the group consisting of wherein X is an alkyl, alkoxy, aryl, a halogen, and mixtures thereof; wherein X is an alkyl, alkoxy, aryl, a halogen, and mixtures thereof; wherein X, Y and Z are independently alkyl, alkoxy, aryl, a halogen, or mixtures thereof, and wherein at least one of Y and Z are present; wherein X, Y and Z are independently alkyl, alkoxy, aryl, a halogen, or mixtures thereof, and wherein at least one of Y and Z are present; and mixtures thereof;a single exposing device for selectively exposing a surface of the electrostatic imaging member to light; anda single electrostatic charging device for charging the surface of the electrostatic imaging member, wherein charge is not accepted by the exposed surface of the electrostatic imaging member and the charge is accepted by the unexposed surface of the electrostatic imaging member, further wherein the exposing device is located before the electrostatic charging device such that the exposing the surface of the electrostatic imaging member to light precedes the charging the surface of the electrostatic imaging member; b) a development component for applying a developer material to the charge-retentive surface to develop the electrostatic latent image to form a developed image on the charge-retentive surface; c) a transfer component for transferring the developed image from the charge-retentive surface to a copy substrate; and d) a fusing component for fusing the developed image to the copy substrate; wherein the electrostatic charging device is located between the exposing device and the development component.
