ABSTRACT:
An image formation apparatus comprises a cleaning member cylindrically formed of a material having elasticity, a moving mechanism for moving both the peripheral face of the cleaning member and the ink discharge face of the print head relative one to another, with both in contact one with another, and a driving control unit for controlling the driving of the moving mechanism. Each time a predetermined number of sheets of the recording medium have images formed thereupon, or each time a predetermined amount of time elapses, following starting of the operations for forming images, the image formation operations are temporarily interrupted, and the moving mechanism is driven under the control of the driving control unit, and the peripheral face of the cleaning member is moved over the surface of the ink discharge face while in contact therewith, thereby suctioning the ink within the ink discharge orifices.
