摘要： PROBLEM TO BE SOLVED: To provide toner for developing an electrostatic charge image, which forms a high-quality and high-reliability image even when the lowest fixing temperature is low. SOLUTION: The toner for developing an electrostatic charge image contains a block copolymer having a low Tg block and a high Tg block, as a binder resin. A temperature T(10 MPa) at which viscosity is 10 4 Pa s under a flow tester application pressure of 10 MPa and a temperature T(1 MPa) at which viscosity is 10 4 Pa s under a flow tester application pressure of 1 MPa satisfy a relation of 20°C≤T(1 MPa)-T(10 MPa).

摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a multi-branched polyester polyol for significantly reducing the conventional temperature for manufacturing and reducing the energy for production, and to provide a resin particle dispersion liquid, an electrostatic charge image developing toner and a method for manufacturing the toner, an electrostatic charge image developer, an image forming method and an image forming apparatus, using a multi-branched polyester polyol produced by the above method. SOLUTION: The method for manufacturing a multi-branched polyester polyol includes a process of at least polycondensation of a hydroxyl acid and/or its protected compound having in total three or more groups of hydroxyl groups, carboxyl groups and their protected groups by using a sulfur acid as a catalyst. A multi-branched polyester polyol manufactured by the above method is used for the resin particle dispersion liquid, the electrostatic charge image developing toner and the method for manufacturing the toner, the electrostatic charge image developer, the image forming method and the image forming apparatus.
