<P>PROBLEM TO BE SOLVED: To provide a developing device, a process cartridge and an image forming apparatus which can yield excellent image quality by preventing surface staining or toner scattering. <P>SOLUTION: The image forming apparatus includes: a first conveying member 53 arranged nearly below a developer carrier 49 to be opposed thereto, and supplying developer to the developer carrier 49 while conveying the developer in a longitudinal direction; and a second conveying member 54 collecting the developer separated from the developer carrier 49, and conveying it in a reverse direction to the first conveying member 53 while stirring it in a direction of a rotary shaft line of the developer carrier 49. An upstream part in the conveying direction of the second conveying member 54 is coupled with a downstream part in the conveying direction of the first conveying member 53 through a feeding part. According as toner in the developer is consumed, the toner is supplied to a downstream side of the second conveying member 54 from a toner replenishing port 30. The developer conveyed by the first conveying member 53 is delivered to the second conveying member 54 through a deliver part 31 so that it may be delivered to the upside of the toner supplied through the toner replenishing port 30. <P>COPYRIGHT: (C)2011,JPO&INPIT |
