An image formation apparatus has an image formation unit that forms toner images on an image holding member. A primary transfer unit transfers toner images on the image holding member onto an intermediate transfer member. A secondary transfer unit transfers toner images on the intermediate transfer member onto a recording medium. An electrically-grounded contact member first comes into contact with the intermediate transfer member downstream from a primary transfer portion. The relationship −2.0≦ln(Vtr)−L/(s×logρ)≦−1.0 is satisfied, in which L (mm) represents the distance from the primary transfer portion to a position where the intermediate transfer member first comes into contact with the contact member, Vtr (V) represents the absolute value of applied voltage to the primary transfer unit, s (mm/sec) represents the moving speed of the intermediate transfer member, and ρ(Ω/□) represents the surface resistivity of the intermediate transfer member.

A combined air-conditioning and hot water supply system simultaneously executes the cooling operation of a use unit and the hot water supply operation of a hot water supply unit, wherein the combined air-conditioning and hot water supply system operates in a cooling priority mode when the temperature differential ΔTwm between a set hot water supply temperature Twset and the inlet water temperature Twi of a plate water-heat exchanger is smaller than a priority operation determination threshold M that is set in advance, and operates in a hot water supply priority mode when the temperature differential ΔTwm becomes equal to or higher than the priority operation determination threshold M. This simultaneous execution of cooling and hot water supply operations prevents hot water from running out.

According to one embodiment, a flow rate adjusting unit is disposed on a gas passageway and includes a valve that adjusts the flow rate of a gas and an actuator that controls the displacement amount of the valve. A displacement amount storage unit stores displacement amount information in which a displacement amount of the valve, used when a gas flows into the gas passageway at a flow rate defined according to a process procedure before performing the process procedure, is obtained in advance for each process procedure. A setting circuit acquires the displacement amount corresponding to the process procedure from the displacement amount storage unit, and controls the actuator on the basis of the acquired displacement amount.
