Abstract:
An image forming method for ejecting a mixed liquid constituted by a plurality of recording liquids from an ejection port while changing supply amounts of the respective recording liquids based on an image signal, and transporting the mixed liquid to an image receiving medium to form an image, said method comprising the steps of:determining a target value of a mixture proportion of said plurality of recording liquids based on said image signal; controlling the supply amounts of the respective recording liquids in such a manner that the mixture proportion of the recording liquids agrees with the target value; detecting an actual value of the mixture proportion in the vicinity of a confluent position of said plurality of recording liquids, during an image forming operation; and comparing the detected actual value with said target value, during the image forming operation, to perform a feedback control of the supply amounts of the respective recording liquids in such a manner that there is no difference between both values.
