Abstract
An image forming apparatus includes lock mechanisms, a regulation processing portion, and a second release processing portion. The lock mechanisms correspond to attachment portions to each of which a developer storage portion is attached, and each regulate detachment of a developer storage portion attached to an attachment portion. When a first state where developer storage portions of a specific type are attached to all the attachment portions, has been detected, and there is a lock mechanism that is not regulating detachment, the regulation processing portion causes the lock mechanism to regulate detachment of the developer storage portion. When a second state where a developer storage portion of the specific type has not been attached to at least one attachment portion, has been detected, and all the lock mechanisms are regulating detachment, the second release processing portion causes all the lock mechanisms to release regulation of detachment.
