Abstract: A printer includes a conveyance unit, a print head, and a braking member. The conveyance unit includes first and second rollers arranged in a state of being in pressure contact with each other with a conveyance path for conveying a long printing medium interposed therebetween, and applies a conveyance force to the printing medium by rotating the first and second rollers. The print head is disposed upstream of a position where the conveyance unit applies the conveyance force in a forward direction along the conveyance path, and performs printing on the printing medium conveyed in the forward direction through the conveyance path.

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.
