PURPOSE:To increase environmental resistance and stability for storage by using a specified kind of calyx (n) allene compound as an effective component. CONSTITUTION:A charging control agent contains an effective component of calyx (n) allene compound as shown by the equation I. In the equation, R1 indicates an allicyclic group, R2 indicates a hydrogen atom, alkyle group with the number of carbons of 1 to 4, or an aryl group, and n indicates an integer of 1 to 8. Also a toner for developing electrostatic charge image is provided with at least one kind of charge control agent as shown by the equation I, a coloring agent and a resin. Namely, the toner may contain one kind of the charge control agent or may contain several kinds of agents. Further the charge control agent of 0.1 to 10 parts by weight is mixed with resin of 100 parts by weight. |
