    摘要： A failure detecting apparatus for a hydraulic circuit of a gearbox includes an operating-state detector. The operating-state detector is configured to detect an operating state of a subject to be controlled with a control-signal pressure output from a solenoid valve. A current setting device is configured to set an electrical current supplied to a solenoid so as to close an output oil passage when a modulator valve is normal and to open the output oil passage when an open failure occurs in the modulator valve, while the solenoid valve is conductive. A failure determining device is configured to detect a failure of the modulator valve when the operating state of the subject to be detected by the operating-state detector is abnormal after a value of the electrical current to be supplied to the solenoid is set at the current setting device.

    摘要： An image forming apparatus includes an image information acquisition unit that acquires image information; a toner image formation unit that forms, in response to a control parameter, a toner image on a surface of an image carrier based on the image information; an image density detection unit that produces a detection result indicative of image density of the toner image; and a control unit that determines whether to use a predetermined region in the toner image formed on the surface of the image carrier based on the image information for a detection of the image density of the toner image, and when the predetermined region is determined to be used for the detection of the image density, corrects the control parameter used by the toner image formation unit based on the detection result so as to maintain the image density in the predetermined region within a predetermined range.

    摘要： A first developer container having a toner supplying opening is provided in a developing unit. A toner concentration sensor is arranged downstream of the toner supplying opening to detect toner concentration in developer. A supply controlling unit is provided to determine an excess or a shortage in the amount of supplied toner based on image information correspondingly to a detection result by the toner concentration sensor, and to correct the driving amount of a toner supplying unit that has been determined based on the image information correspondingly to the recognized excess or shortage in the amount of supplied toner.
