Image formation apparatus and inkjet recording apparatus

An inkjet recording apparatus, comprising:

• a treatment liquid deposition unit which deposits treatment liquid onto a recording medium;
• an image formation unit including:
• a cylindrical conveyance member which conveys the recording medium on which the treatment liquid has been deposited by the treatment liquid deposition unit, 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;
• an ink ejection head which ejects ink 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 ink 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 ink 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;
• and
• a drying unit which dries the ink having been deposited on the recording medium in the image formation unit.
