摘要： A sheet conveying device includes a support configured to move between a storage position and a full open position and including a pair of rollers, a plurality of contact bodies, and a switching unit. The switching unit switches the pair of rollers in response to contact of the plurality of contact target bodies included in the switching unit, with the plurality of contact bodies. The plurality of contact bodies includes a first contact body closer to the storage position than the plurality of contact target bodies with the support at the full open position and closer to the full open position with the support at the storage position, and a second contact body closer to the storage position than a part of the plurality of contact target bodies with the support at a halfway position and closer to the full open position with the support at the storage position.

摘要： A fixing device includes a belt, a pad, a pressure rotator, a lubricant supplier, and a collector. The belt forms a loop. The pad is inside the loop of the belt and contacts the belt. The pressure rotator presses the belt against the pad to form a fixing nip between the belt and the pressure rotator. The lubricant supplier supplies lubricant to an inner face of the belt. The collector collects the lubricant. The collector has a first end and a second end. The first end contacts an inner face of one end of the belt in a width direction of the belt. The second end contacts the inner face of another end of the belt opposite to the one end in the width direction.

摘要： A fixing device includes a belt, a nip formation pad, and a pressure rotator. The belt has a loop rotatable in a sheet conveyance direction. The nip formation pad is inside the loop and includes three curved portions in the sheet conveyance direction. The three curved portions form a nip formation face. The pressure rotator presses the belt against the nip formation pad to form a fixing nip between the belt and the pressure rotator.

摘要： An image forming apparatus includes an image forming unit for forming an image on a medium; and an application device for applying a treatment liquid to the medium. The application device includes a conveying roller; an application roller for applying the liquid; a squeeze roller for reducing the thickness of the liquid on the application roller; and a tray for supplying the liquid to the squeeze roller. In the application operation, the application and squeeze rollers come in contact, and a valley formed by these rollers faces upward. In the standby condition, at least one of the application and squeeze rollers is moved to such a position that the valley faces laterally. The tray always covers the lower side of the application and squeeze rollers in regions near the longitudinal end portions of the application roller, which end portions do not come in contact with the conveying roller.
