Abstract
A developing device configured to develop a latent image formed on a surface of an image bearer includes a rotator, a bearing, a holder, a first regulator, and a second regulator. The rotator includes a rotation shaft. The bearing supports the rotation shaft. The holder holds the bearing. The first regulator, disposed on any one of the bearing and the holder, regulates movement of the bearing such that the bearing does not fall toward one end side in an axial direction of the rotation shaft relative to the holder. The second regulator regulates movement of the bearing such that the bearing does not fall toward another end side in the axial direction relative to the holder after the bearing is attached to the holder.
