Patent ID: 8889324

Claim:
An image bearing member comprising: an electroconductive substrate; and a photosensitive layer provided overlying the electroconductive substrate, the photosensitive layer comprising at least one charge transport materials selected from the group consisting of a naphthalene tetracarboxylic acid diimide-isoindol derivative represented by the following chemical structure 1, a naphthalimide-isoindol derivative represented by the following chemical structure 2, and a triphenyl amine-isoindol derivative represented by the following chemical structure 3, where R 1 and R 2 independently represent a hydrogen atom, a substituted or non-substituted alkyl group, an alkoxy group, a substituted or non-substituted aromatic hydrocarbon group, a halogen atom, and a nitro group, k represents an integer of 1 to 4, and 1 represents an integer of from 1 to 5, and R 3 represents a substituted or non-substituted alkyl group, a substituted or non-substituted cycloalkyl group, and a substituted or non-substituted aromatic hydrocarbon group, where R 1 , R 2 , and R 4 independently represent a hydrogen atom, a substituted or non-substituted alkyl group, an alkoxy group, a substituted or non-substituted aromatic hydrocarbon group, a halogen atom, and nitro group, k represents an integer of 1 to 4, 1 represents an integer of from 1 to 5, and m represents an integer of 1 to 6, and where R 1 , R 2 , R 5 , and R 6 independently represent a hydrogen atom, a substituted or non-substituted alkyl group, an alkoxy group, a substituted or non-substituted aromatic hydrocarbon group, a halogen atom, and nitro group, k represents an integer of 1 to 4, and 1, n, and p represent integers of from 1 to 5.
