ABSTRACT:
A toner contains at least a binder resin, a colorant, a compound (A) and a compound (B) in which the compound (A) is selected from the specific compound group and the compound (B) is a derivative of any one of the compounds included in the group from which the compound (A) is selected. The total content A of the compound (A) and compound (B) in the toner is from 0.2% to 6% by weight based on the weight of the toner, and where the content of the cross-linking agent component in the binder resin is represented by B % by weight based on the weight of the toner, the following relationship is satisfied: 0.1≦A/B≦70.
