The purpose of the present invention is to prevent the flow of air flowing from the outside of a cover part into the cover part via an ink droplet passing hole as air accompanying printing droplets outflows. An inkjet recording device is provided with: a recording mechanism (printing mechanism) having an ink room 101 that ejects an ink column 107, charging electrodes 103A and 103B that charge ink droplets 106 generated from the ink column 107, and deflection electrodes 105A and 105B that deflect charged ink droplets 106A; and a cover part 118 that has an ink droplet passing hole 117 through which the ink droplets 106A deflected by the deflection electrodes 105A and 105B pass and covers the recording mechanism. The inkjet recording device causes the ink droplets 106A to land onto a recording object 116 that moves relative to a recording head 100 to perform recording. A vent hole 130 is provided in a lateral surface of the cover part 118.

An inkjet recording apparatus includes an ink container. The ink container stores an ink for printing on a printing object. The inkjet recording apparatus also includes a stirring mechanism. The stirring mechanism stirs the ink stored in the ink container. The stirring mechanism includes a stationary shaft and a rotating body. The rotating body rotates around the stationary shaft. The stationary shaft and rotating body are placed in a lower part of the ink container.

An image recording apparatus includes a controller configured to make a transition of an operational mode of the controller between a first mode and a second mode. The first mode represents an operational state where a contract for a service using a first cartridge has been made. The second mode represents an operational state where the contract for the contract for the service has not been made. In the first mode, the controller stores a first tank liquid volume and a second tank liquid volume in a memory. The first tank liquid volume represents, when the first cartridge is attached to an attachment case, an amount of liquid supplied from the first cartridge and stored in a tank. The second tank liquid volume represents, when a second cartridge is attached to the attachment case, an amount of liquid supplied from the second cartridge and stored in the tank.
