Abstract
A developing device includes a transporting unit that rotates while facing an image carrier that carries an electrostatic latent image, the transporting unit transporting developer toward the image carrier; a feeding unit that contacts the transporting unit to feed the developer to the transporting unit; a transport path that connects a containing chamber that contains the developer to a feeding chamber that houses the feeding unit; a supplying unit that retains the developer to be supplied in the transport path and supplies the developer to the feeding unit in a supply region that is separated from a contact region in which the feeding unit contacts the transporting unit; and an attaching unit that is disposed downstream of the contact region and upstream of the supply region in a rotation direction of the feeding unit and that attaches the developer to the feeding unit at a location below the contact region.
