PURPOSE:To obtain a sharp image by incorporating a specific cation compd. at 0.01-10pts.wt. into 100pts.wt. binder resin. CONSTITUTION:The cation compd. expressed by the formula I is incorporated at 0.01-10pts.wt. into 100pts.wt. binder resin. In the formula I, R1-R4 respectively denote hydrogen, chlorine, bromine, hydroxyl, alkoxy or carboxyl or 1-4C; A denotes alkylene of 1-5C or -C6H4-CH2-; m denotes 0 or 1; n denotes 1 or 2; K<+> denotes the compd. expressed by the formula II. In the formula II, R5 denotes a single bond, carbamoyl, alkyl of 1-2C, benzyl, cyclohexyl, etc.; R6, R7 denote alkyl or alkylene of 1-4C; W denotes -CO-, etc.; An<-> denotes anion. The sharp image which is free from scumming and toner splashing is thereby obtd. |
