Abstract:
1. An image formation apparatus, comprising: a cylindrical conveyance member which conveys a recording medium in a conveyance direction while rotating in a state where the recording medium is held by suction on a circumferential surface of the cylindrical conveyance member; a liquid ejection head which ejects liquid from an ejection face thereof toward the recording medium being conveyed by the cylindrical conveyance member; and an ejection face protective device which is disposed in a periphery of the ejection face of the liquid ejection head, the ejection face protective device including a restricting member which restricts floating up of the recording medium by coming in contact with the recording medium at a position in one of a first region between the ejection face of the liquid ejection head and the circumferential surface of the cylindrical conveyance member, and a second region adjacent to the first region, when the recording medium is released from the suction toward the circumferential surface of the cylindrical conveyance member while being conveyed by the cylindrical conveyance member, a movement device which changes a relative positional relationship of the ejection face protective device and the ejection face of the liquid ejection head, wherein when the recording medium is released from the suction toward the circumferential surface of the cylindrical conveyance member, the movement device moves the ejection face protective device to the position in the one of the first region and the second region.
