摘要： Disclosed is a positively chargeable toner comprising, as a charge-controlling agent, an acid adduct, metal complex or derivative of a 2-­alkylimidazole represented by the following formula:
wherein R₂ stands for an alkyl group having 11 through 17 carbon atoms, and R₄ stands for a hydrogen atom or a methyl group. In this toner, a high charge-controlling effect is attained with a small amount of the charge-controlling agent, and since the charge-controlling agent has a white color or light color, this toner is advantageously used as an electrostatic photographic toner for the color printing.
