Abstract
PURPOSE: To simplify preparation without impairing the superior characteristics of liquid developer, by using a pigment, a highly insulating carrier fluid, and a specified polymer complex as main components.
CONSTITUTION: A (meth) acrylic acid ester of aliphatic alcohol with 6 or more carbon atoms and 20 mole % or less (meth) acrylic acid are copolymerized in a highly insulating carrier fluid to form a polymer A. A (meth) acrylic acid ester of aliphatic alcohol with 6 or less carbon atoms, 50 mole % a (meth) acrylic acid ester of aliphatic alcohol with 6 or more carbon atoms, and 20 mole % or less glycidyl methacrylate are similarly copolymerized in a carrier fluid. The polymer B obtained is highly concentrated and mixed with the solution of polymer A in a state dissolved in the carrier fluid to make reaction. The solution of the polymer complex thus obtained by epoxy ring opening reaction and esterification reaction is diluted and pigments are added.
