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.
