PURPOSE:To secure such an electrophotographic sensitizer that is high in sensitivity and excellent in durability by containing a specific sterile compound in it. CONSTITUTION:It contains a new sterile compound being shown in an equation I. Where, in this equation I, R<1>-R<3> show a hydrogen atom, an alkyl group capable of having a substituent, an alkenyl group, an aralkyl group, an aryl group, and A shows a di-aromatic ring capable of having the substituent or heterocyclic residual group, and Z<1>, Z<2> shown an atomic group being required to form saturated 5-6 rings together with two carbonic atoms of indoline rings. With this constitution, such an electrophotographic sensitizer that is high in sensitivity and excellent in durability is thus securable. |
