The present invention provides a charge control agent containing, as an active substance(s), one or two or more rhodanine compounds represented by the following formula (1).
where R1 represents a hydrogen atom, etc.; R2 represents a hydrogen atom, a linear or branched alkyl group having 1 to 8 carbon atoms which may have a substituent, a substituted or unsubstituted heterocyclic group, etc.; R3 to R7, which may be identical to or different from each other, represent a hydrogen atom, a linear or branched alkyl group having 1 to 10 carbon atoms which may have a substituent, a linear or branched alkyloxy group having 1 to 20 carbon atoms which may have a substituent, etc., and 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 nitrogen atoms which do not have the substituents of R3 to R7.
本发明提供了一种包含以下式(1)所表示的一种或两种或更多罗丹宁化合物作为活性物质的电荷控制剂。其中R1代表氢原子等;R2代表氢原子、具有1至8个碳原子的线性或支链烷基基团,该基团可能具有取代基,取代或未取代的杂环基团等;R3至R7(它们可以相同也可以不同)代表氢原子、具有1至10个碳原子的线性或支链烷基基团,该基团可能具有取代基,具有1至20个碳原子的线性或支链烷氧基基团,该基团可能具有取代基等,并且它们可以相互连接形成环;V、W、X、Y和Z代表碳原子或氮原子,V、W、X、Y和Z中的任意0至3个是不具有R3至R7的取代基的氮原子。
