Abstract:
A disclosed maintenance management system includes an upper-limit information storage unit configured to store an upper limit of usage for each component identifier of a component, which upper limit is expressed by using an accumulated number of revolutions of a photoconductive drum in an image forming apparatus; a revolution number information acquiring unit configured to acquire a number of revolutions of the photoconductive drum used in the image forming apparatus; and an alarm output unit configured to calculate the accumulated number of revolutions of the used photoconductive drum, calculate a component service life predictive value by using the upper limit stored in the upper-limit information storage unit for each component identifier, and output an alarm including component information pertaining to the corresponding component identifier in the event that the component service life predictive value is less than or equal to a remainder day reference value.
