Title:
ELECTROPHOTOGRAPHIC PHOTORECEPTOR, METHOD FOR MANUFACTURING SAME, AND ELECTROPHOTOGRAPHIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/142608
Kind Code:
A1
Abstract:
Provided are an electrophotographic photoreceptor in which a combination of a charge generation material and an electron transportation material is improved, a method for manufacturing the electrophotographic photoreceptor, and an electrophotographic device. An electrophotographic photoreceptor including an electroconductive substrate 1 and a photosensitive layer provided on the electroconductive substrate. The photosensitive layer includes at least a charge generation material and an electron transportation material. The electron transportation material includes first and second electron transportation materials. The difference between the LUMO energy of the first electron transportation material and the LUMO energy of the charge generation material is in the range of 1.0-1.5 eV. The difference between the LUMO energy of the second electron transportation material and the LUMO energy of the charge generation material is in the range of 0.6-0.9 eV. The proportion of the second electron transportation material content in relation to the total of the first electron transportation material content and the second electron transportation material content is in the range of 3-40% by mass.
