ABSTRACT:
An image forming device including: an image holding member; a charging member; a latent image-forming unit; a developing unit that develops the electrostatic latent image formed on the image holding member with a developer including a toner and a carrier, the toner comprising an external additive having first inorganic particles with a volume average particle diameter of 80 nm to 300 nm, and the carrier including a core material having a magnetic powder dispersed in a resin and a resin covering layer that covers the core material; a transfer unit; a removal unit; and an aggregation-forming unit that, by contacting a surface of the charging member and rotating in accordance with rotation of the charging member, removes adherents on the surface of the charging member, including the first inorganic particles, from the surface of the charging member, and forms aggregations in which the removed first inorganic particles are aggregated.
