<p>PROBLEM TO BE SOLVED: To provide an electrostatic charge image developing toner which does not require pulverization or classification processes, which shows sufficiently sharp distribution of the grain size without containing coarse particles and which has excellent transfer property so that a good image can be stably obtained, and to provide a method of manufacturing the toner. SOLUTION: In the electrostatic charge image developing toner manufacturing method comprising a drying process, a loop type pneumatic conveying dryer is used in the drying process in which air flow 7 whose temperature is >=70 deg.C and line velocity is >=30 m/s is supplied to the loop 1 of the pneumatic conveying dryer and the air flow temperature at the toner collecting part 5 of the dryer is controlled to <=60 deg.C. Preferably, by supplying second air flow whose temperature is <=50 deg.C through a second air flow supply port 8 disposed between the loop part 1 and the toner collecting part 5, the temperature of the air flow between the second air flow supply port 8 and the toner collecting part 5 is controlled to <=60 deg.C.</p> |
