Abstract
An image forming apparatus includes a state management unit that shifts an authentication state from a non-login state to a login state, a storage unit that stores setting information, and a data management unit that, in a case where a free space of the storage unit is less than a threshold value, deletes the setting information stored in the storage unit at a timing of shifting from the non-login state to the login state and secure a free space greater than or equal to the threshold value in the storage unit.
