An inkjet recording apparatus comprising: a tank that has at least one ink chamber, into which an ink is retained, and at least one injection inlet through which the ink is injected into the ink chamber; a recording unit that is configured to eject the ink retained in the ink chamber and to record an image on a sheet; a remaining amount sensor that is configured to output a first remaining amount signal or a second remaining amount signal, depending on an amount of ink retained in the ink chamber; a display unit on which information is displayed; an operation unit that is configured to accept a user's operation and to output a first operation signal or a second operation signal in response to the accepted user's operation; and a controller that is configured to control an operation of the recording unit and an operation of the display unit; wherein the operation unit is configured to output the first operation signal when the operation unit accepts a first operation, which is a type of the user's operation, the first operation being performed to indicate that an ink has been injected, and the second operation signal when the operation unit accepts a second operation, which is a type of the user's operation, the second operation being performed to indicate that no ink has been injected, and characterized in that the controller is configured to perform inquiry processing in which if a completion signal by which completion of ink injection is capable of being presumed is output and the first remaining amount signal, which is effected when the amount of ink is equal to or larger than a remaining amount threshold, is also output from the remaining amount sensor, the controller displays, on the display unit, inquiry information to ask whether an ink has been injected and accepts the first operation or the second operation through the operation unit, and notification processing in which if the completion signal is output and the second remaining amount signal, which is effected when the amount of ink is smaller than the remaining amount threshold, is also output from the remaining amount sensor, a prompt to inject an ink is indicated on the display unit. a tank that has at least one ink chamber, into which an ink is retained, and at least one injection inlet through which the ink is injected into the ink chamber; a recording unit that is configured to eject the ink retained in the ink chamber and to record an image on a sheet; a remaining amount sensor that is configured to output a first remaining amount signal or a second remaining amount signal, depending on an amount of ink retained in the ink chamber; a display unit on which information is displayed; an operation unit that is configured to accept a user's operation and to output a first operation signal or a second operation signal in response to the accepted user's operation; and a controller that is configured to control an operation of the recording unit and an operation of the display unit; wherein the operation unit is configured to output the first operation signal when the operation unit accepts a first operation, which is a type of the user's operation, the first operation being performed to indicate that an ink has been injected, and the second operation signal when the operation unit accepts a second operation, which is a type of the user's operation, the second operation being performed to indicate that no ink has been injected, and characterized in that the controller is configured to perform inquiry processing in which if a completion signal by which completion of ink injection is capable of being presumed is output and the first remaining amount signal, which is effected when the amount of ink is equal to or larger than a remaining amount threshold, is also output from the remaining amount sensor, the controller displays, on the display unit, inquiry information to ask whether an ink has been injected and accepts the first operation or the second operation through the operation unit, and notification processing in which if the completion signal is output and the second remaining amount signal, which is effected when the amount of ink is smaller than the remaining amount threshold, is also output from the remaining amount sensor, a prompt to inject an ink is indicated on the display unit.
