Abstract
A developing device develops a latent image on an image carrier by using a developer. The device includes a developer carrier that faces the image carrier and is configured to rotate while magnetically holding developer on its outer circumferential surface. The device also includes a magnetic member elongated along a rotational direction of the developer carrier to form a gap that surrounds the outer circumferential surface. The magnetic member overlaps an end of a developing region in a direction of a rotational axis of the developer carrier, when viewed from a direction perpendicular to the rotational axis. When a side of the magnetic member close to a center of the developer carrier is divided into first and second sides and located downstream and upstream in the rotational direction, respectively, the first side is set back further from the center than a position where the first and second sides meet.
