PROBLEM TO BE SOLVED: To provide a toner for electrophotography that suppresses the generation of fog even after long-term printing with a large change in printing ratio, thereby forming a high quality image over a long period of time. SOLUTION: The toner for electrophotography contains toner base particles containing a binder resin and a colorant, and an external additive to be externally added to the toner base particles, and the external additive includes surface treated particles obtained by surface treating resin fine particles with a fatty acid metal salt.
