PROBLEM TO BE SOLVED: To provide an image forming apparatus capable of suppressing the leakage of a developer in a cartridge having a large capacity and an image forming system.SOLUTION: The image forming apparatus includes a cartridge attachment part 2B to which one of a small-capacity cartridge including a first developing roller and a first supply roller and a large-capacity cartridge 28H storing toner T more than the small-capacity cartridge and including a second developing roller 31H and a second supply roller 33H can be selectively attached and a controller. When it is determined that the small-capacity cartridge is attached, the controller drives the first supply roller, so that a conveyance force for the toner T is a first conveyance force. When it is determined that the large-capacity cartridge 28H is attached, the controller drives the second supply roller 33H, so that the conveyance force for the toner T is a second conveyance force smaller than the first conveyance force. |
