Toner producing method

A toner producing method comprising:

• dispersing, in an aqueous medium, an oil phase including a release agent and either or both of a binder resin and a binder resin precursor;
• and
• washing a slurry obtained by the dispersing and subjecting the slurry to a heat treatment to obtain toner,
• wherein:
• the binder resin includes a crystalline polyester and an amorphous polyester,
• the heat treatment is performed at 40° C. or more and 50° C. or less, and
• the toner comprises:
• the binder resin;
• and
• the release agent,
• in a measurement result of a first temperature rise obtained by measurement through differential scanning calorimetry (DSC) of the toner before undergoing a storage treatment below, one or more peaks as an endothermic component are present in a temperature region lower than a peak derived from the crystalline polyester;
• and
• the toner satisfies expression (1) below;
• where a glass transition temperature of the toner is defined as Tg [C] and Tg−5° C. is defined as Ta [° C.], the toner is stored at Ta [° C.] and humidity of 50% RH for 24 hours, provided that the glass transition temperature Tg of the toner corresponds to a glass transition temperature of the toner before undergoing the storage treatment,
• 1.5<H1−H2<4.5[J/g] expression (1),
• where, in the expression (1), H1 is a total endothermic amount of an endothermic amount of the peak derived from the crystalline polyester and an endothermic amount of the one or more peaks present in the temperature region lower than the peak derived from the crystalline polyester in the measurement result of the first temperature rise obtained by measurement through DSC of the toner before undergoing the storage treatment, and
• H2 is a total endothermic amount of an endothermic amount of a peak derived from the crystalline polyester and an endothermic amount of a peak present in a temperature region lower than the peak derived from the crystalline polyester in a measurement result of a first temperature rise obtained by measurement through the DSC of the toner after undergoing the storage treatment, provided that when the endothermic amount of the peak present in the temperature region lower than the peak derived from the crystalline polyester is zero, the H2 is the endothermic amount of the peak derived from the crystalline polyester.
