摘要： A belt-type transport device includes a belt, a pressure unit, a nip forming unit, a belt stretching roller, an inclination controller, a contact unit, and a support unit. The belt is an endless belt, has an outer circumferential surface and an inner circumferential surface, and is to be rotated. The pressure unit is in contact with the outer circumferential surface of the belt. The nip forming unit presses the belt against the pressure unit so as to form a nip through which a recording medium is to be transported. The belt stretching roller is disposed inside the belt and stretches the belt. The inclination controller controls inclination of the belt stretching roller. The contact unit is provided along a width direction of the belt and is in contact with the inner circumferential surface of the belt. The support unit supports the contact unit such that the contact unit is able to follow inclination of the belt which is changed due to the inclination of the belt stretching roller.

摘要： An image processing apparatus includes an acquisition unit, a first detection unit, a first determination unit, a second detection unit, a second determination unit, a correction unit, and a transmitting unit. The acquisition unit acquires image information having multiple pixels. The first detection unit detects sub-scanning-direction boundary pixels in accordance with the image information. The first determination unit determines whether or not a development-related defect occurs in a preset number of pixels downstream of the sub-scanning-direction boundary pixels in the sub-scanning direction. The second detection unit detects an end pixel in the main scanning direction. The second determination unit determines whether or not each of sub-scanning-direction boundary pixels arranged in the main scanning direction is close to the end pixel in the main scanning direction. The correction unit corrects the image information. The transmitting unit transmits the image information corrected by the correction unit to an image forming apparatus.

摘要： An image forming apparatus includes a transfer unit and a pair of measuring units. The transfer unit transfers an image onto at least one recording medium by applying a voltage between the at least one recording medium and the image along a thickness direction of the at least one recording medium. Before the transfer unit applies the voltage, the pair of measuring units measure respective electrical resistance values of a front surface and a rear surface of the at least one recording medium in a direction crossing the thickness direction.

摘要： A developing device includes first and second developing rollers, a trimmer, a divider, and a movement regulator. The first and second developing rollers are arranged so as to face an outer peripheral surface of a photoconductor at downstream and upstream positions, respectively, in a rotation direction of the photoconductor, and respectively include first and second sleeves and first and second magnets. The trimmer is arranged so as to face an outer peripheral surface of the first developing roller, and regulates formation of a layer of developer held by the first developing roller. The divider divides the developer regulated by the trimmer into developer that adheres to the first developing roller and developer that adheres to the second developing roller. The movement regulator is disposed between the trimmer and the divider and regulates movement of the developer held by the first developing roller before the developer is divided.
