摘要： An image forming apparatus includes an image forming mechanism and an image fixing unit. The image forming mechanism forms a toner image on a recording sheet. The image fixing unit fixes the toner image onto the recording sheet. The image fixing unit includes a magnetic flux generator, a heat member, a magnetic flux adjuster, and a controlling member. The magnetic flux generator generates a magnetic flux. The heat member is heated inductively by the magnetic flux generated by the magnetic flux generator. The magnetic flux adjuster reduces the magnetic flux active on the heat member to form a heat reduction area in an outer circumferential surface of the heat member in a width direction thereof. The controlling member moves the magnetic flux adjuster to change the heat reduction area.

摘要： A fixing device includes a stationary member, a roller, an endless belt, a pressure rotator, and a lubricant applicator. The endless belt is stretched over the stationary member and the roller. The pressure rotator is disposed opposite the stationary member via the endless belt to form a fixing nip between the pressure rotator and the endless belt on the stationary member. The lubricant applicator contacts the roller over an entire length of the roller in an axial direction of the roller. The lubricant applicator contacts an inner surface of the endless belt and has an axial length equal to or greater than an axial length of the stationary member.

摘要： A stand for a thin display includes a vertical position adjustment mechanism; and a switchover mechanism for switching over between a vertical orientation and a horizontal orientation of a thin display. When the switchover mechanism has rotated the thin display, the vertical position adjustment mechanism has different movement ranges between the vertical orientation and the horizontal orientation. Accordingly, when the thin display is in a vertical orientation, the lower end of the thin display does not hit against a base, which provides a easy and reliable operation even in a vertical orientation or in a horizontal orientation.

摘要： An image forming apparatus at least includes: a component, detachable from the image forming apparatus, including a driven portion; first and second detectors configured to detect an installation of the component in the image forming apparatus and driving of the driven portion, respectively; an indicator device configured to communicate information to a user; and a controller to control the indicator device. In a circumstance in which neither an occurrence of installation nor driving of the driven portion are detected, the controller outputs a first notification requesting a proper installation of the component when a first count of occurrences of the first notification or a second count of occurrences of cancellation of the first notification is less than first and second reference values, respectively, and a second notification requesting repair when the first count or the second count equals the first and second reference values, respectively.

摘要： A pressure lever includes an oscillating edge that is capable of contacting a supporting shaft of a pressure roller. An oscillating lever includes a plurality of oscillating edges around a fixed edge. An elastic unit is latched between the fixed edge of the oscillating lever and an immovable portion, and biases the oscillating lever towards one of the rollers. A position of the fixed edge of the oscillating lever is capable of being changed in a state of being deviated from a position before oscillating based on an oscillating position of the oscillating lever separately from an oscillation of the fixed edge.
