Abstract
Disclosed herein is an electrophotographic imaging member comprising a supporting substrate and a charge generating layer. The charge generating layer comprises a binder, a first pigment having a first photosensitivity, and a second pigment having a second photosensitivity that is at least 2% greater than the photosensitivity of the first pigment. The first pigment has the same chemical formula, visible spectrum and crystalline structure as the second pigment. An electrostatographic apparatus including the electrophotographic imaging member also is disclosed.
Claims22
An electrophotographic imaging member comprising a supporting substrate and a charge generating layer, the charge generating layer comprising a binder and a first pigment having a first photosensitivity and a second pigment having a second photosensitivity that is at least 2% greater than the first photosensitivity of the first pigment, the first pigment having the same chemical formula, visible spectrum and crystalline structure as the second pigment.
A coating system for a charge generating layer of an electrophotographic imaging member, the coating system comprising a mixture of a binder, a solvent, a first pigment having a first photosensitivity and a second pigment having a second photosensitivity that is at least 2% greater than the first photosensitivity of the first pigment, the first pigment having the same chemical formula, visible spectrum and crystalline structure as the second pigment.
An electrostatographic apparatus comprising a charging component, an electrophotographic imaging member, a transfer component, a development component, and a fixing component, the electrophotographic imaging member including a supporting substrate and a charge generating layer, the charge generating layer comprising a binder and a first pigment having a first photosensitivity and a second pigment having a second photosensitivity that is at least 2% greater than the first photosensitivity of the first pigment, the first pigment having the same chemical formula, visible spectrum and crystalline structure as the second pigment.
A method of forming an electrophotographic imaging member, comprising:
- obtaining a substrate,
- combining a first pigment having a first photosensitivity and a second pigment having a second photosensitivity that is at least 2% greater than the first photosensitivity of the first pigment with a binder to form a pigment-binder mixture, the first pigment having the same chemical formula, visible spectrum and crystalline structure as the second pigment, and
- coating the pigment-binder mixture on the substrate.
