At the time of an end of an image forming job (YES of S1), a controller causes a blade and a developing roller to be separated from a photosensitive drum (S2). At that time, the controller controls separation timing of the belt and the developing roller so that the developing roller is separated from the photosensitive drum before a surface position of the photosensitive drum contacted to the developing roller at a contact position at the time of a start of separation of the blade from the photosensitive drum reaches a developing position with the separation of the blade. According to this, even when a liquid accumulation reaches the developing position depending on the separation of the blade, the developing roller has already been separated from the photosensitive drum before the liquid accumulation reaches the developing position and therefore, the liquid accumulation is not collected by the developing roller. When the liquid accumulation is not collected by the developing roller, color mixture due to the liquid accumulation does not occur.
