Abstract
A target selection portion selects one target attachment portion out of a plurality of attachment portions, and selects, when a detection state regarding a target storage unit attached to the target attachment portion out of a plurality of developer storage units changes from a developer-remaining state to a developer-empty state, a new target attachment portion as the target attachment portion. A notification processing portion executes, when a first notification mode is selected, empty state notification processing for outputting information representing the developer-empty state to a notification destination every time the developer-empty state of the target storage unit is detected. The notification processing portion executes, when a second notification mode is selected, the empty state notification processing when the developer-empty states of some of the plurality of developer storage units are detected.
