Consumption information management apparatus, image formation apparatus, and consumption information management system |
摘要 |
An integration density acquiring unit for a consumption information management apparatus acquires integration density from an image signal sent from an image processing section, and an information converting unit calculates a quantity of consumed toner (consumption information) by multiplying the integration density by a specified coefficient to send the quantity to a cumulative consumption information calculating unit. The cumulative consumption information calculating unit temporarily stores the information for the quantity of toner consumption in a memory, and reads out the information from the memory at predetermined timing. Accordingly, it is possible to determine only the cost for developer used by a user or calculate the quantity of developer remaining within an image formation apparatus based on the cumulative consumption information for the unadjusted developer stored in the memory.
