ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, AND ELECTROPHOTOGRAPHIC APPARATUS AND PROCESS CARTRIDGE EACH INCLUDING THE ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18047300 titled 'ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER, AND ELECTROPHOTOGRAPHIC APPARATUS AND PROCESS CARTRIDGE EACH INCLUDING THE ELECTROPHOTOGRAPHIC PHOTOSENSITIVE MEMBER
Simplified Explanation
The patent application describes an electrophotographic photosensitive member, which includes several layers including a support, a charge-generating layer, a first hole-transporting layer, and a second hole-transporting layer. The second hole-transporting layer contains specific hole-transportable compounds.
- The second hole-transporting layer contains a hole-transportable compound represented by the formula (1) and a hole-transportable compound represented by the formula (2) and/or formula (3).
- The mass of the compounds represented by formulas (1), (2), and (3) are denoted as W1, W2, and W3 respectively.
- The value calculated from the expression (I) is between 0.05% by mass and 5.0% by mass.
- The expression (II) is satisfied, where the ratio of (W2+W3) to (W1+W2+W3) multiplied by 100 is within the specified range.
- The energy value of the highest occupied molecular orbital (HOMO) for the compounds represented by formulas (1) and (2) are denoted as CTM1HOMO and CTM2HOMO respectively.
- The absolute difference between CTM2HOMO and CTM1HOMO is between 0.05 eV and 0.30 eV.
Potential Applications

Original Abstract Submitted
Provided is an electrophotographic photosensitive member including a support, a charge-generating layer, a first hole-transporting layer, and a second hole-transporting layer, wherein the second hole-transporting layer contains a hole-transportable compound represented by the formula (1) (mass: W1, energy value of the highest occupied molecular orbital: CTM1HOMO), and a hole-transportable compound represented by the formula (2) (mass: W2) and/or a hole-transportable compound represented by the formula (3) (mass: W3) (energy value of the highest occupied molecular orbital: CTM2HOMO), wherein a value calculated from the expression (I) is from 0.05% by mass to 5.0% by mass, and wherein the expression (II) is satisfied: (W2+W3)/(W1+W2+W3)×100 (% by mass)—Expression (I); and 0.05 (eV)≤|CTM2HOMO|-|CTM1HOMO|≤0.30 (eV)—(II).
