Abstract
Provided is a technology relating to an image forming apparatus configured to calculate a toner usage amount per day. The image forming apparatus stores the calculated toner usage amount per day in a list when a toner usage history is permitted to be stored, and avoids storing the calculated toner usage amount per day in the list when the usage history is inhibited from being stored. When the toner usage history is permitted to be stored, the image forming apparatus extracts a feature amount indicating a toner consumption tendency exhibited by a user based on the toner usage amount per day corresponding to a predetermined period stored in the list, and avoids extracting the feature amount when the toner usage history is inhibited from being stored.
