(57) [Problem] To provide a stable high-quality image without contaminating each member of an electrophotographic recording apparatus with a developer even in long-term continuous printing, and to develop a developing unit, a photoconductor unit, and the like. Long life, and one-component developer, Provided is an electrophotographic toner which is excellent in any of two-component developers and is particularly suitable for full-color development, a developer using the same, and an image forming method. SOLUTION: In an electrophotographic toner comprising at least a binder resin, a colorant and an external additive, the binder resin is a polyester resin and / or a polyol resin, and the external additive is treated with methyl hydrogen silicone oil. Was Inorganic fine particles having an average primary particle diameter of 100 nm or less, and having a methyl hydrogen silicone oil release rate of 30% An electrophotographic toner characterized by the following. |
