Title:
CHARGE CONTROL AGENT AND TONER USING SAME
Document Type and Number:
WIPO Patent Application WO/2015/046214
Kind Code:
A1
Abstract:
[Problem]
To provide a charge control agent and a toner having a superior charging characteristic.
[Solution]
A charge control agent containing a bis-phthalimide derivative represented by formula (1). Thus, it is possible to provide a safe, negative chargeability charge control agent with which the rate of rise of the charge can be increased, and which has a high charging amount and poses no problem in terms of waste regulations. Furthermore, it is possible to provide a negatively chargeable toner (and particularly, a negatively chargeable polymerized toner) for electrostatic image development which uses this charging control agent and has a superior charging characteristic.
