Title:
トナー用結着樹脂組成物
Document Type and Number:
Japanese Patent JP7089437
Kind Code:
B2
Abstract:
To provide a toner binder resin composition having high paper versatility even in high-speed printing, and a method for manufacturing an electrophotographic toner using the binder resin composition.SOLUTION: A toner binder resin composition includes amorphous polyester AH, amorphous polyester AL and crystalline polyester C. The amorphous polyester AH and the amorphous polyester AL are a poly condensate between an alcohol component and a carboxylic component in the nonexistence of gallic acid; the softening point of the amorphous polyester AH is higher by 20°C or more than that of the amorphous polyester AL; the crystalline polyester C is a poly condensate between an alcohol component including aliphatic diol having carbon atoms of 4 or more and 12 or less in the presence of the gallic acid and a carboxylic component including an aliphatic dicarboxylic acid based compound having carbon atoms of 10 or more and 16 or less, and a method for manufacturing an electrophotographic toner uses the binder resin composition.SELECTED DRAWING: None
