Summary:PROBLEM TO BE SOLVED: To provide a toner that can be used at a desired fixing temperature and to provide the toner having properties including excellent document offset and heat adhesion. SOLUTION: The process for producing a toner composition includes processes of: melt-mixing an amorphous resin, a crystalline resin, an optional wax, and a colorant to form a toner; pelletizing the toner; continuously annealing the pelletized toner by heating the toner to a temperature of from 50°C to 90°C for a period of time from 2 minutes to 60 minutes, the temperature being above the glass transition temperature of the toner; processing the annealed toner to form toner particles; and recovering the resulting toner particles.
