Abstract
An image forming apparatus includes image bearers, developing devices, developer containers, and developer supply devices. The image bearers are arranged side by side along a movement direction of an intermediate transferor or a sheet. The developing devices, the developer containers, and the developer supply devices are configured to be rearrangeable for each color in the movement direction in a manner that one or each of a developing device, a developer container, and a developer supply device corresponding to each color of the different colors is detached from and attached to the image forming apparatus, separately from a rest of the developing device, the developer container, and the developer supply device. The image forming apparatus is configured to be available for use when colors of the developing device, the developer container, and the developer supply device correspond to each other after rearrangement.
