Abstract
A developing device includes a case, a developer holder, a suction duct and a carrier catcher. The case accommodates a developer containing a toner and a carrier. The developer holder is disposed so as to face an image holder disposed outside the case and supplies the developer to the image holder. The suction duct sucks and collects a scattered toner floating in a space around the developer holder. The carrier catcher is formed in a vertical direction and disposed on a lower surface of a path of the suction duct.
