PROBLEM TO BE SOLVED: To provide a carrier used for a developer that can perform sufficient charge control of image quality required in the field of production printing, can supply a stable amount of developer to a development area, and is used in an electrophotographic method and an electrostatic recording method for enabling continuous paper feed at a printing density of a low image area ratio in a high-speed machine using a low-temperature fixing toner.SOLUTION: There is provided a carrier comprising a resin layer including at least one or more types of fine particles, wherein at least one type of the fine particles are composed of fine particles of barium sulfate; in Ba analysis of the carrier by X-ray photoelectron spectroscopy (XPS), the amount of Ba detected is 0.3 atomic% or more, and the equivalent circle diameter of fine particles of the barium sulfate is 400 nm or more and 900 nm or less.SELECTED DRAWING: None |
