<p>PROBLEM TO BE SOLVED: To provide an excellent electrostatic charge image developing toner which causes neither increase of surface stain (fog) of a white background nor lowering of image density when repeatedly used in a copying machine, a printer or the like and has such durability and stability as to ensure neither increase fog nor scattering in a machine even if the toner deteriorates with age when it is allowed to stand in a hot environment. SOLUTION: In the electrostatic charge image developing toner comprising at least a bonding resin, a colorant and a charge controlling agent, the charge controlling agent is a compound of formula (1) (where R is a 5-25C saturated or unsaturated monovalent aliphatic group).</p> |
