    • A highly sensitive positively charged type electrophotographic photoconductor includes an organic compound that transports electrons efficiently, improving light emission efficiency. The photoconductor is used in an electrophotographic drum, an electrophotographic cartridge and an electrophotographic apparatus. The photosensitive layer includes at least one compound represented by the following general formula (I) wherein each of R1, R2, R3 and R4, is independently selected from the group consisting of hydrogen atoms, alkyl groups having 1-6 carbon atoms that optionally have substituents and aryl groups that optionally have substituents, each of R5 and R6 is independently selected from the group consisting of hydrogen atoms, alkyl groups having 1-6 carbon atoms that optionally have substituents, aryl groups that optionally have substituents and heterocyclic groups that optionally have substituents, R7 is selected from the group consisting of halogen atoms, alkyl groups having 1-6 carbon atoms that optionally have substituents, aryl groups that optionally have substituents and heterocyclic groups that optionally have substituents, m represents an integer of 0 to 2 and a plurality of R7s are the same or different, the substituents being selected from a group consisting of halogen atoms, alkyl groups having 1-6 carbon atoms, alkoxy groups having 1-6 carbon atoms, aryl groups, and heterocyclic groups.
