Abstract: An image forming apparatus includes a sensor that acquires first and second data groups of paper characteristics by measuring a recording medium; a processor that determines a parameter for controlling at least one of image formation and conveyance of a recording medium on a conveyance path based on the first and second data groups acquired by the sensor; an image former that forms an image on a recording medium conveyed on the conveyance path based on the parameter. The processor compares the first and second paper characteristic data groups, the first paper characteristic data group has been measured at a first time period and the second paper characteristic data group has been measured at a second time period nearer to a present time than the first time period, and the processor controls the image formation based on a the comparison result.

Abstract: Provided is a recording medium detection device which prevents a recording medium from jamming. The device comprises: a first roller and a second roller which nip and transport a recording medium; a roller shaft which rotatably supports the second roller; a shaft support; and a displacement detector. The shaft support supports the roller shaft movably in the thickness direction of the recording medium. The displacement detector detects displacement of the second roller in the thickness direction. The shaft support further supports the second roller movably in the transportation direction of the recording medium through the roller shaft.

Abstract: An improved image forming apparatus is described which can inhibit the quality of printed images from being degraded. A control unit performs a steering operation to shift an intermediate transfer belt toward a target belt position by controlling the inclination angle of a steering roller. Also, a memory stores the inclination angle of the steering roller in association with the operational states of rotary members facing the intermediate transfer belt. The control unit updates the values stored in the memory with an update value. When the result of detecting the belt edges indicate that the intermediate transfer belt falls in a predetermined range around the target belt position during the steering operation, the control unit determines the update value on the basis of the steering duration time and the inclination angle of the steering roller.
