Abstract:
An image forming apparatus includes either one of a process cartridge and a development device. The process cartridge is attachable to and detachable from the image forming apparatus, and integrally includes the development device. The development device includes a developer supplying member and a developer carrying member, at least one of which is formed of an elastic material, and which rotate in contact with each other. The developer supplying member is provided to be displacable in directions of contacting with and separating from the developer carrying member, and is biased toward the developer carrying member by predetermined biasing force.
