A liquid developer for electrostatic images which comprises at least one charge controlling agent selected from the group consisting of compounds represented by formula (I) or (II) and complex salts containing a molecular structure shown by the formula (I) or (II): ##STR1## wherein R.sup.1 and R.sup.2 each represents a hydrogen atom, an alkyl and substituted alkyl group, an aryl and a substituted aryl group, an aralkyl group, an aliphatic acyl group, an aromatic acyl group, an alkylsulfonyl group, an arylsulfonyl group, R.sup.1 and R.sup.2 represent identical group or different groups, or R.sup.1 and R.sup.2 together form a heterocyclic ring with the nitrogen atom in the formulae, and when one of R.sup.1 and R.sup.2 represents a hydrogen atom, the other represents a group other than a hydrogen atom; A represents an alkylene group or a substituted alkylene group; X represents a hydrogen atom, a monovalent to tetravalent metal atom, a quaternary ammonium cation, and n represents a positive integer of 1 to 4, and when X represents the metal atom defined above and the number represented by n is not sufficient to satisfy the valence of the metal atom represented by X, the residual metal valence bond or bonds are occupied with one or more ligands to form the complex salt.
一种用于静电图像的液态显影剂,包括至少一种选自以下化合物组合的电荷控制剂:公式(I)或(II)所表示的化合物和含有公式(I)或(II)所示的分子结构的复合盐:##STR1## 其中R.sup.1和R.sup.2分别表示氢原子,烷基和取代烷基,芳基和取代芳基,芳基烷基,脂肪族酰基,芳香族酰基,烷基磺酰基,芳基磺酰基,R.sup.1和R.sup.2表示相同的基团或不同的基团,或R.sup.1和R.sup.2共同形成具有氮原子的杂环环,当R.sup.1和R.sup.2中的一个表示氢原子时,另一个表示除氢原子以外的基团; A表示烷基或取代烷基; X表示氢原子,一价至四价金属原子,季铵阳离子,n表示1至4的正整数,当X表示上述定义的金属原子且n所表示的数字不足以满足X所表示的金属原子的价数时,剩余的金属价键或键被一个或多个配体占据以形成复合盐。
