ABSTRACT:
An image forming apparatus performs an image forming operation by driving a ejecting element of a recording head with an ink ejecting drive voltage for ejecting ink, detects a temperature of ink to be flown into the recording head and a temperature of ink to be discharged respectively with a first temperature detection section and a second temperature detection section, and corrects the ink ejecting drive voltage on the basis of a temperature of ink being heat-transferred with the ejecting element, which is estimated with a predetermined conversion formula on the basis of the detected ink temperatures, for controlling an ink amount to be ejected.
