    • An image forming apparatus includes an apparatus body, a recording head, a head tank, a displacement member, an air release unit, a main tank, a liquid feed device, a body-side detector, and a supply controller. The supply controller controls a normal filling operation to start feeding liquid from the main tank to the head tank without opening the air release unit when a consumption amount of the liquid in the head tank is a threshold amount or greater, and stop feeding the liquid from the main tank to the head tank when the body-side detector detects an arrival of the displacement member at a normal fill position. When the body-side detector detects the displacement member at a start of the normal filling operation, the supply controller corrects the normal fill position to a position at which the liquid feed device can feed the liquid to the head tank.

    • Provided is a convenient leak detector which has high detection sensitivity and can quickly start a leak test after the start of vacuuming a test piece, without impairing the capabilities such as fast response to helium gas. The leak detector includes a mass spectrometer tube configured to detect a search gas and a turbo-molecule pump which has a plurality of stages rotors and stators alternately arranged in a housing, the rotors attached to a rotary shaft, and includes a drive source configured to rotationally drive the rotary shaft. An intake port communicating with a test piece TP and a connection port to which the mass spectrometer tube is connected are opened at positions away from each other in a wall surface of the housing, the wall surface facing a rotor of the uppermost stage.
