    Publication number: 20180329330
    Abstract: An electrophotographic toner set, an image forming apparatus, and an image forming method include a developer toner and a replenishment toner. The developer toner and the replenishment toner each include toner particles, and silica particles and titania particles provided on the surfaces of the toner particles. The silica particles have a BET specific surface area of 15 to 95 m2/g and are surface-treated with a silicone oil. The relationship between the content of the silica particles of the developer toner and the content of the silica particles of the replenishment toner, and the relationship between the content of the titania particles of the developer toner and the content of the titania particles of the replenishment toner each have particular values.
