Abstract: A developing device includes: a housing, a refill developer storage part, a developing roller, a developer conveyance path, a developer receiving port, a conveyance member, and a magnetic member. The developing roller is driven into rotation in the developing housing and carries a toner on a circumferential surface thereof. The toner is conveyed inside the first conveyance path and the second conveyance path of the developing housing in a circulating manner. A first stirring screw is disposed on the first conveyance path and conveys the toner in a first direction. Downstream of the toner refill port, a magnet is arranged. The magnetic member forms a magnetic brush from a top panel of the developing housing towards the first stirring screw. A refill toner flowed-in through the toner refill port is so conveyed as to fall below the magnetic brush whereby the refill toner is favorably stirred with a surrounding toner.

Abstract: A developing device has a developer container, a first stirring member, and a first stirring chamber. The developer container stores toner. The first stirring member conveys toner while stirring it. The first stirring chamber is in the developer container. The first stirring member is in the first stirring chamber. In a top surface of the first stirring member is a toner supply port through which toner is supplied from outside by action of gravity. The first stirring member has, on the downstream side of the toner supply port in the toner conveying direction, a reduced conveying power portion exerting reduced conveying power to toner. The first stirring chamber has a developer stagnation portion at a position facing the reduced conveying power portion. The inner surface of the developer stagnation portion has a smaller surface roughness than the inner surface of the stirring chamber except for the developer stagnation portion.

Abstract: A developer replenishing apparatus includes a developer housing container and a sensor. The developer housing container includes a container main body having a wall that partitions an internal space, a shaft section arranged so as to extend in a first direction in the internal space, a moving wall which moves from an upstream side to a downstream side in the first direction along the shaft section and which conveys the developer, and a developer discharge port which is arranged near a downstream end in the first direction of the container main body. The sensor is arranged at a position that enables the sensor to generate different outputs between before and after the moving wall reaches a prescribed position on a movement route. The determining unit determines a state where there is no developer in the developer housing container when the sensor generates an output determined in advance.
