Claims
- 1. A charge-transporting material comprising a phenothiazine or phenoxazine derivative represented by the following general formula (1): ##STR36## wherein Ar.sup.1 and Ar.sup.2 are the same or different and each represents an aryl group which may have one or more substituents selected from the group consisting of a lower alkyl group, a lower alkoxy group, a halogen atom, a diarylamino group, and a dialkylamino group; R.sup.1 and R.sup.2 are the same or different and each represents a hydrogen atom, a lower alkyl group, or an aryl group which may have one or more substituents selected from the group consisting of a lower alkyl group, a lower alkoxy group, a halogen atom, a diarylamino group, and a dialkylamino group; R.sup.3 represents a lower alkyl group, an alicyclic hydrocarbon group having 5 to 7 carbon atoms, an aryl group which may have one or more substituents selected from the group consisting of a lower alkyl group, a lower alkoxy group, a halogen atom, a diarylamino group, and a dialkylamino group, or an aralkyl group which may have one or more substituents selected from the group consisting of a benzyl group, a tolylmethyl group, a methoxybenzyl group, and a chlorobenzyl group; X represents a sulfur atom or an oxygen atom; and n and m each represents an integer of 0 or 1, wherein a lower alkyl group has from 1 to 4 carbon atoms and a lower alkoxy group has from 1 to 3 carbon atoms.
- 2. A charge-transporting material that comprises the phenothiazine or phenoxazine derivative represented by the general formula (I) of claim 1 and a binder resin.
- 3. An electrophotographic photoreceptor containing a charge-transporting material comprising a phenothiazine or phenoxazine derivative represented by the following general formula (1): ##STR37## wherein Ar.sup.1 and Ar.sup.2 are the same or different and each represents an aryl group which may have one or more substituents selected from the group consisting of a lower alkyl group, a lower alkoxy group, a halogen atom, a diarylamino group, and a dialkylamino group; R.sup.1 and R.sup.2 are the same or different and each represents a hydrogen atom, a lower alkyl group, or an aryl group which may have one or more substituents selected from the group consisting of a lower alkyl group, a lower alkoxy group, a halogen atom, a diarylamino group, and a dialkylamino group; R.sup.3 represents a lower alkyl group, an alicyclic hydrocarbon group having 5 to 7 carbon atoms, an aryl group which may have one or more substituents selected from the group consisting of a lower alkyl group, a lower alkoxy group, a halogen atom, a diarylamino group, and a dialkylamino group, or an aralkyl group which may have one or more substituents selected from the group consisting of a benzyl group, a tolylmethyl group, a methoxybenzyl group, and a chlorobenzyl group; X represents a sulfur atom or an oxygen atom; and n and m each represents an integer of 0 or 1, wherein a lower alkyl group has from 1 to 4 carbon atoms and a lower alkoxy group has from 1 to 3 carbon atoms, and further wherein said electrophotographic photoreceptor comprises an electrically conductive support carrying a charge-transporting material and a charge-generating material, which are in the same or separate layers, wherein the charge-transporting material comprises a phenothiazine or phenothiazine derivative represented by the above general formula (1).
