A liquid ejection apparatus, including: a conveyor mechanism; a recording head; a treatment-liquid application portion; a sealing mechanism for selectively taking a sealing state in which an ejection space is sealed or an unsealing state in which the ejection space is not sealed; a humid-airy supply mechanism for performing a humidifying operation to produce and supply the humid air into the ejection space in the sealing state; a forcible discharge mechanism for performing a forcible discharge operation for forcibly discharging recording liquid from the head; and a maintenance control section for, when a time elapsed from an occurrence of a jam to a clearance of the jam is less than a first time, performing the forcible discharge operation, and for, when the time is equal to or greater than the first time, performing the humidifying operation in the sealing state and then performing the forcible discharge operation.
