Abstract
To provide: a charge control agent having negative chargeability, which contributes to environmental conservation and the like to an increased degree, has high performance (high charge amount, quick rise-up of charge, excellent stability with time, and high environmental stability), and has improved dispersibility; a toner for developing an electrostatic charge image containing the charge control agent; and an image forming method and an image forming apparatus each using the toner for developing an electrostatic charge image. A charge control agent for controlling a charged state of powder, characterized by including one or more units each represented by the following chemical formula (1) in a molecule.
