Abstract:
1. A monitoring apparatus comprising: a determining unit that determines in advance a first target amount, which is determined as a target of consumption amount of a colorant at a first timing based on a target time indicating a desired usage period of the colorant, at which a first predetermined period from start of use of the colorant in image formation has elapsed; a timer that measures a time from start of use of the colorant in image formation; a first calculating unit that calculates an actual amount of the colorant actually consumed while the timer measures the first predetermined period; and an announcing unit that announces consumption status information generated by comparing the first target amount and the actual amount, wherein the determining unit determines the first target amount based on a second target amount, which is determined as a target of consumption amount of the colorant at a second timing, at which a second predetermined period from start of use of the colorant in image formation has elapsed, the second predetermined period being longer than the first predetermined period.
