PURPOSE:To obtain the toner for electrophotography with which electrostatic charge impartation is uniformly executed and which has excellent electrostatic chargeability by combining a compd. classified as 'C.I. Solvent Yellow 16, 56, 60 or C.I. Solvent Blue 14(R)' or a binder resin for the toner. CONSTITUTION:The 'C.I. Solvent Yellow 16, 56, 60 or C.I. Solvent Blue 14(R)' is used in the binder resin for the toner as the constituting component. The oil soluble dye classified as the 'C.I. Solvent Yellow 16, 56, 60 or C.I. Solvent Blue 14(R)' dissolves well in the binder resin for the toner and uniformizes the charge control agent components in the individual fine toner particles. The toner having the uniform electrostatic chargeability is obtd. without generating unequalness in electrostatic charge impartation. |
