摘要： An image forming apparatus includes an exhaust duct to guide air inside the image forming apparatus to an outside of the image forming apparatus. A positive ion generator emits a positive ion into the exhaust duct. A negative ion generator emits a negative ion into the exhaust duct. The negative ion generator is shifted from the positive ion generator in one of an air flow direction of the air moving inside the exhaust duct and a direction perpendicular to the air flow direction.

摘要： A nip forming device includes an endless belt that is flexible and rotates and a nip former that is disposed opposite an inner circumferential face of the endless belt. A pressure rotator presses against the nip former via the endless belt to form a nip between the endless belt and the pressure rotator, through which a conveyed object is conveyed. A separator is disposed downstream from the nip in a conveyance direction of the conveyed object. The separator separates the conveyed object from the endless belt. The separator includes a non-contact portion separated from the endless belt and a contact portion that contacts the endless belt. The contact portion retains a gap having a predetermined size between the non-contact portion and the endless belt.

摘要： A fixing device includes a first rotator, a second rotator, a heater, a nip formation pad, and a separator. The second rotator contacts an outer circumferential surface of the first rotator to form a nip between the first rotator and the second rotator. The heater includes a resistive heat generator to heat the first rotator. The nip formation pad contacts an inner circumferential surface of the first rotator to form the nip. The separator separates a recording medium passing through the nip from the first rotator. The separator includes a separating surface and a contact. The separating surface is separated from the outer circumferential surface of the first rotator and separates the recording medium from the first rotator. The contact contacts the outer circumferential surface of the first rotator at a position where the first rotator is pinchable between the contact and the nip formation pad.

摘要： A fixing device includes an endless fixing rotator, a heater, a nip formation pad, and a pressure rotator. The heater is disposed opposite an inner circumferential surface of the fixing rotator to heat the fixing rotator. The nip formation pad is disposed opposite the inner circumferential surface of the fixing rotator that is slidable over the nip formation pad. The pressure rotator is configured to press against the nip formation pad via the fixing rotator to form a fixing nip through which a recording medium bearing a toner image is conveyed while being sandwiched between the fixing rotator and the pressure rotator. The nip formation pad includes a base and a thermal equalizer having a thermal conductivity higher than a thermal conductivity of the base. The nip formation pad has a nip face opposite the fixing nip. The thermal equalizer is disposed in at least part of the nip face.

摘要： In an initial state where a push rod is pressed down, a base of a movable contact point board supporting a movable contact point makes contact with inclined protruding portions of a moving block by a second spring to be inclined. When the movable contact point makes contact with a fixed contact point following the projecting of the push rod, the base makes contact with stoppers. Thereafter, since the moving block alone rises, the movable contact point board rotates following the end edges of the stoppers according to release of the pressing by the protruding portion. Thereby the movable contact point largely slides and is displaced to the fixed contact point.

摘要： In a fixing device, a controller switches a pressing member between a pressure application state to contact the pressing member against a fixing member and a pressure release state to separate the pressing member from the fixing member. The controller starts rotation of the pressing member before the pressing member contacts the fixing member in the pressure application state, when the pressing member switches from the pressure release state to the pressure application state. An oil applier includes an oil pan and an oil regulating member. The oil pan is provided under the pressing member to contain oil in which the pressing member is dipped. The oil regulating member is provided downstream from the oil pan in a direction of rotation of the pressing member to contact the pressing member to regulate an amount of oil adhering to the pressing member.
摘要翻译：在定影装置中，控制器在压力施加状态之间切换按压构件，以将压紧构件接触固定构件和压力释放状态，以将按压构件与固定构件分离。当按压构件从压力释放状态切换到压力施加状态时，控制器在加压构件在压力施加状态下接触固定构件之前开始按压构件的旋转。一种油涂器包括油盘和油调节件。油底壳设置在按压部件的下面，以容纳浸入按压部件的油。油调节部件沿着按压部件的旋转方向设置在油盘的下游，以接触按压部件，以调节附着在按压部件上的油量。
