摘要：
An image forming apparatus calculates an ink temperature considering a thermal capacity near nozzles and an ink circulation flow quantity of a circulation pump in addition to an ink temperature when flowing into a recording head and an ink temperature when flowing out of the recording head, and accurately estimates a waste amount of the ink ejected from the nozzles in, e.g., maintenance processing other than image formation.
