Abstract

To provide a toner that can be fixed to cloth and has excellent image robustness and heat-resistance storage properties.SOLUTION: A toner has at least maleic acid-modified polyolefin having a polypropylene block in a main chain, and silica particles. The content of the maleic acid-modified polyolefin is 5 mass% or more and 25 mass% or less relative to a mass obtained by excluding a colorant from the toner. The silica particles are present inside the toner. The average particle diameter of the silica particles is larger than 1 μm.SELECTED DRAWING: None
