A developing device of the present invention has a toner supply opening in a first carrying path and in the upstream of the developer carrying direction of a first carrying screw which is further from a developing roller; and a moquette member having feathers on its surface, and being provided, along the developer carrying direction, on the first carrying path. With this arrangement, it is possible to realize a compact developing device having a simple arrangement in which the supplied toner is speedily mixed with the preexisted developer, and the stable toner which is uniformly dispersed and charged can be speedily supplied for development.
