摘要： An image forming apparatus includes an apparatus body, a recording head, a sub tank, a carriage, a main tank, a liquid feed device, a displacement member, a first detector, a second detector, a detection retainer, a liquid consumption amount measuring device, and a supply controller. The measuring device measures a consumption amount of liquid in the sub tank when the displacement member displaces from a first position in a direction in which the consumption amount of liquid in the sub tank decreases. When a detection output of the first detector continues to be, for a predetermined time or number of times, in a detection state in which the first detector detects the displacement member and shifts from the detection state to a non detection state in which the first detector does not detect the displacement member, the measuring device starts measuring the consumption amount of liquid in the sub tank.

摘要： An image forming apparatus includes: a print head; a head tank; a carriage; a main tank; a pump; a displaceable member or feeler; a first sensor; a second sensor; a controller to supply an amount of liquid ink corresponding to the displacement difference amount of the feeler to the head tank; and an environmental condition detector. The controller stores the environmental condition when the displacement difference amount is stored; corrects the stored displacement difference amount when a change in a current environmental condition relative to the stored environmental condition is more than a previously set first threshold amount and below a previously set second threshold amount being larger than the first threshold amount; and detects and stores the displacement difference amount again when the change in the current environmental condition relative to the stored environmental condition exceeds the second threshold amount.
