PROBLEM TO BE SOLVED: To provide a manufacturing method for toner for electrophotography for achieving excellent fixation performance at low temperatures and thermal insulating storage performance simultaneously and achieving excellent productivity and to provide the toner for electrophotography manufactured by the method. SOLUTION: This manufacturing method for the toner for electrophotography comprises a process [process (1)] for heating and holding a toner composition containing crystalline polyester, amorphous polyester, and binding resin. The process (1) comprises a process (A): the toner composition is heated and held at heating temperature Tra(°C) indicated by the expression (i): Tm-70≤Tra<Tm-20 (wherein, Tm denotes the highest peak temperature in heat absorption in the differential scanning quantity of heat measurement of the toner composition) and a process (B): the heated and held substance obtained in the process (A) is heated and held at heating temperature Trb(°C) being higher than heating temperature Tra(°C) by 10-70°C.
