Method for producing electrostatic charge image developing toner

A method for producing an electrostatic charge image developing toner, the method comprising:

• forming aggregated particles by aggregating at least resin particles in a dispersion liquid containing the resin particles;
• and
• fusing/coalescing the aggregated particles by heating an aggregated particle dispersion liquid containing a base having volatility and the aggregated particles dispersed therein in a fusion/coalescence tank that houses the aggregated particle dispersion liquid,
• wherein in fusing/coalescing the aggregated particles, at least one of conditions (1) to (3) below is satisfied,
• Condition (1):
• the fusion/coalescence tank has one or plural openings in an upper portion thereof, and the total area ratio of the openings is 5 cm2/m3 or more per unit amount of the aggregated particle dispersion liquid,
• Condition (2):
• the aggregated particles are fused/coalesced in the fusion/coalescence tank in a state of reduced pressure within a range of (atmospheric pressure−0.5) kPa or less,
• Condition (3):
• the aggregated particles are fused/coalesced in a state where a gas is blown into the fusion/coalescence tank with a wind volume of 5 L/(min·m3) or more per unit amount of the aggregated particle dispersion liquid in the fusion/coalescence tank.
