17  5,460,919  18  R$_{18}$, R 19 , R 20 ,  and  R$_{21}$ ,  a saturated 5-membered or 6-mem› bered ring is preferred and examples thereof are pyrrolidine,  piperidine, morpholine, and piperazine.  In formula (C-IV),  Q$_{1 }$ represents a nonmetallic atomic  group necessary for forming an aromatic nitrogen-contain- ing heterocyclic ring such as pyridine, quinoline, isoquino› line, acridine, pyridazine, pirimidine, pyrazine, cinnoline,  quinazoline, quinoxaline, phthalazine, and phenazine. These  aromatic nitrogen-containing ring may be substituted with  an alkyl group such as methyl, ethyl, propyl, butyl, etc., a  halogen atom, an alkoxy group, a hydroxy group, a carbam› oyl group, an acetyl group, or an amino group.  Specific examples of the compounds shown by formulae  (C-Il), (C-Ill), and (C-IV), which are preferably used for the  developer of the present invention, are shown below but the  invention is not limited to these compounds.
