A developing device includes a developer carrying member for carrying a developer comprising a toner and a carrier, a magnet provided inside the developer carrying member, a developing chamber for feeding the developer to the developer carrying member, and a feeding member rotatably provided in the developing chamber for feeding the developer in the developing chamber. A non-magnetic blade member regulates an amount of the developer to be coated on said developer carrying member, and a route forming portion forms a route for feeding a developer in the developing chamber. The magnet is opposed to a region inside of the developer carrying member from a downstream end of an opposing portion to the blade member with the rotational direction of said developer carrying member so as to attract the developer on the region.
