When receiving a command to record an image on a recording medium, controlling means causes recovering means to execute a recovery operation, and then recording means to execute image recording when an elapsed time from the execution of a previous recovery operation measured by clocking means exceeds a predetermined time and a coverage rate of a recording part calculated by coverage rate calculating means exceeds a predetermined value. The controlling means causes the recording means to execute image recording without causing the recovering means to execute the recovery operation when the coverage rate of the recording part calculated by the coverage rate calculating means is not more than the predetermined value.
