Abstract:
1. A developing device that develops a latent image on an image carrier with use of developer including particles with magnetic properties, the developing device comprising: a developer carrier that is provided so as to face the image carrier, and configured to rotate while magnetically holding the developer on an outer circumferential surface thereof; and a magnetic member that is elongated along a rotational direction of the developer carrier so as to surround the outer circumferential surface of the developer carrier with a gap therebetween, wherein when viewed from a direction perpendicular to a rotational axis of the developer carrier, the magnetic member overlaps an end of a developing region of the developer carrier in a direction of the rotational axis, and when a side of the magnetic member close to a center of the developer carrier in the direction of the rotational axis is divided into a first side located downstream in the rotational direction and a second side located upstream in the rotational direction, the first side is set back further from the center of the developer carrier than a position where the first and second sides meet each other.
