Method for producing electrostatic charge image development toner

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

• a first step of aggregating polyester resin particles and a flat color material to produce a first aggregated particle dispersion in which first aggregated particles having a number-average particle diameter of 1 μm or more are dispersed;
• a second step of adding a non-crystalline resin particle dispersion in which non-crystalline resin particles are dispersed with the first aggregated particle dispersion to cause the non-crystalline resin particles to be attached to the first aggregated particles and obtain second aggregated particles, wherein the second step includes adding the non-crystalline resin particle dispersion to the first aggregated particle dispersion two or more times, a solid content concentration of the non-crystalline resin particle dispersion satisfies Formula (4),
• solid content concentration of the non-crystalline resin particle dispersion added for (n)th time<solid content concentration of the non-crystalline resin particle dispersion added for (n+1)th time, Formula (4):
• wherein n is an integer of 1 or more;
• and
• a third step of heating a second aggregated particle dispersion in which the second aggregated particles are dispersed to cause the second aggregated particles to coalesce,
• wherein the non-crystalline resin particle dispersion satisfies Formulae (1) to (3),
• −0.01×A−0.25×B+9.2≤pH≤−0.01×A−0.25×B+10.0 Formula (1):
• 100 nm≤A≤250 nm Formula (2):
• 5 mgKOH/g≤B≤20 mgKOH/g, Formula (3):
• wherein A is a particle diameter of the non-crystalline resin particles, B is an acid value of the non-crystalline resin, and pH is a pH of the non-crystalline resin particle dispersion.
