摘要： A maintenance device used in a liquid discharge head includes a first cap to seal a nozzle face of the liquid discharge head, a second cap disposed outside the first cap, and a humidity conditioner disposed outside the first cap and inside the second cap. The second cap seals the first cap and at least a contact portion between the nozzle face of the liquid discharge head and the first cap. The humidity conditioner adjusts humidity in a space between the first cap and the second cap.
