    Abstract: A hydrazone derivative of triphenylamine is represented by general formula (1). In general formula (1), R1 and R2 each represent, independently of one another, at least one chemical group selected from the group consisting of a halogen atom, an optionally substituted alkyl group having a carbon number of at least 1 and no greater than 6, an optionally substituted alkoxy group having a carbon number of at least 1 and no greater than 6, and an optionally substituted aryl group having a carbon number of at least 6 and no greater than 12. In general formula (1), m and n each represent, independently of one another, an integer of at least 0 and no greater than 4. In general formula (1), 1 represents 0 or 1.

    Abstract: An electrophotographic photosensitive member (1) includes a conductive substrate (2) and a photosensitive layer (3). The photosensitive layer (3) is a single-layer photosensitive layer (3c) containing a charge generating material and an electron transport material. The electron transport material includes a compound represented by general formula (1) shown below. An amount of charge of calcium carbonate as measured by charging the calcium carbonate through friction with the photosensitive layer (3) is at least +7.0 μC/g. In general formula (1), R1 and R2 each represent, independently of each other, a halogen atom, for example. Further, m, n, and Y are as described in the description.
