Abstract:
1. A charge control agent containing, as an active substance(s), one or two or more thiazolidinedione derivatives represented by the following formula (1): wherein R 1 represents a hydrogen atom, a linear or branched alkyl group having 1 to 8 carbon atoms which may have a substituent, a cycloalkyl group having 5 to 10 carbon atoms which may have a substituent, a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted heterocyclic group or a substituted or unsubstituted condensed polycyclic aromatic group; R 2 represents a hydrogen atom, a linear or branched alkyl group having 1 to 8 carbon atoms which may have a substituent, a cycloalkyl group having 5 to 10 carbon atoms which may have a substituent, a linear or branched alkenyl group having 2 to 6 carbon atoms which may have a substituent, a linear or branched alkyloxy group having 1 to 8 carbon atoms which may have a substituent, a cycloalkyloxy group having 5 to 10 carbon atoms which may have a substituent, a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted condensed polycyclic aromatic group or a substituted or unsubstituted aryloxy group; R 3 to R 7 , which may be identical to or different from each other, represent a hydrogen atom, a deuterium atom, a fluorine atom, a chlorine atom, a bromine atom, an iodine atom, a hydroxy group, a cyano group, a nitro group, a linear or branched alkyl group having 1 to 10 carbon atoms which may have a substituent, a cycloalkyl group having 5 to 10 carbon atoms which may have a substituent, a linear or branched alkenyl group having 2 to 6 carbon atoms which may have a substituent, a linear or branched alkyloxy group having 1 to 8 carbon atoms which may have a substituent, a cycloalkyloxy group having 5 to 10 carbon atoms which may have a substituent, a substituted or unsubstituted aromatic hydrocarbon group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted condensed polycyclic aromatic group or a substituted or unsubstituted aryloxy group, and R 3 to R 7 may be joined to each other to form a ring; and V, W, X, Y and Z represent a carbon atom or a nitrogen atom and 0 to 3 of any of V, W, X, Y and Z are a nitrogen atom which does not have substituents of R 3 to R 7 .
