Abstract: 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.

Abstract: A transport device includes a first belt member, a second belt member, a first roller, a second roller, a third roller, a fourth roller, a fifth roller, and a sixth roller. The second belt member is in contact with the first belt member to form a contact portion in cooperation with the first belt member. The first roller is capable of adjusting a tilt in a longitudinal direction of the first roller. The second roller is capable of adjusting a tilt in a longitudinal direction of the second roller. The third and fourth rollers are located adjacent to the first roller. The fifth and sixth rollers are located adjacent to the second roller. The third roller, the fourth roller, the fifth roller, and the sixth roller each have a uniform diameter in a longitudinal direction of the roller, and are disposed at positions other than the contact portion.

Abstract: A liquid applying device includes a circulation member, an impregnation member, and a support member. The circulation member is configured to circulate in a predetermined direction. The impregnation member is formed in a plate shape. The impregnation member is impregnated with a liquid. The impregnation member is in contact with the circulation member at an end portion thereof in a direction intersecting with a circulating direction of the circulation member so as to apply the liquid to the circulation member. The support member supports a portion including an end portion side of the impregnation member, at an opposite side of the circulation member in a state where the end portion of the impregnation member is in contact with the circulation member.

Abstract: 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.

Abstract: A heating device includes a belt member that is rotated, plural heating elements that are arranged in a width direction of the belt member and generate heat so as to heat the belt member, plural resistance elements that have positive temperature coefficients and are connected to the plural heating elements such that each of the plural resistance elements is connected in series with a corresponding one of the plural heating elements, and a base material that includes a heat-conductive metal layer and a pair of heat-resistant metal layers between which the heat-conductive metal layer is interposed and has a surface on which the plural heating elements and the plural resistance elements are disposed. A temperature of the belt member is reduced by an increase in resistances of the plural resistance elements caused by an increase in temperatures of the plural resistance elements.
