Abstract
A monitoring device is configured to monitor image recordation by a recorder using a recording material supplied from a first cartridge and a second cartridge. the monitoring device includes a memory and a controller. The controller is configured to obtain number-of-sheet information indicating a number of sheets on which the image recordation has been performed, first consumption amount information indicating a consumption amount of a recording material consumed from the first cartridge, and second consumption amount information indicating a consumption amount of a recording material consumed from the second cartridge, determine ratio information indicating a ratio of the recording material consumed from the second cartridge to a total consumption amount of the recording material consumed from the first and second cartridges based on the obtained first and second consumption amount information, and store the obtained number-of-sheet information and the determined ratio information in the memory.
