Abstract
A developing device includes: an magnetic field generating unit that generates an magnetic field; and a cylindrical developer holder, to which a voltage is applied, that surrounds the magnetic field generating unit and rotates, the cylindrical developer holder: having an outer circumferential surface having a plurality of grooves that extend in a direction of a rotational axis, the outer circumferential surface being capable of holding developer including a magnetic substance by using the magnetic field generated by the magnetic field generation unit, an electrical resistance of an inner wall surface of each of the grooves being higher than an electrical resistance of the magnetic substance included in the developer; and supplying the developer to an image holder that holds an electrostatic latent image.
