A device management apparatus includes a storage device configured to store a number of fed sheets in an early failure period, the number of fed sheets in the early failure period being a certain number of fed sheets and being a preset number of fed sheets, which is treated as an early failure where the maintainable component has a failure, and calculates a failure density depending on a number of fed sheets based on a number of fed sheets at a time when a failure occurred in the component, which is received from the multiple image forming apparatuses, and outputs information about replacement of the maintainable component based on the failure density to the number of fed sheets in the early failure period from a number of fed sheets at a time when the parameter exceeds the threshold after an operation, which is received from one image forming apparatus.
