摘要： A fixing device includes a fixing belt and a pressure rotator that presses against a nip formation pad via the fixing belt to form a fixing nip between the pressure rotator and the fixing belt. A first holder holds a first lateral end of the fixing belt in an axial direction thereof. A second holder holds a second lateral end of the fixing belt in the axial direction thereof. The second holder, together with the first holder, defines a holder interval provided between the first holder and the second holder in the axial direction of the fixing belt. A lubricant supplying sheet impregnated with a lubricant is sandwiched between the nip formation pad and the fixing belt at the fixing nip. The lubricant supplying sheet has a sheet span in the axial direction of the fixing belt. The sheet span is within the holder interval.

摘要： An image forming apparatus includes an oil input device and a fixing device including a fixing member, a pressing member, and an oil applier. In the oil applier, an oil application member applies oil supplied from an oil supply mechanism to one of the fixing member and the pressing member. In the oil supply mechanism, an oil supply member provided adjacent to an oil storage member supplies oil sent from the oil storage member to the oil application member. When the fixing device is reattached to the image forming apparatus after the fixing device is detached from the image forming apparatus, oil sent from the oil input device through an oil inlet overflows the oil storage member, and is supplied to one of the oil supply member and the oil application member provided adjacent to the oil storage member before an image forming operation starts.

摘要： An image forming apparatus includes two rotators, a driver driving the rotators, a heating device to heat the rotator, a blower blowing air to the heating device, a temperature detector, a recording medium detector, a cover, an open-close detector, and circuitry. The circuitry detects an abnormal state and stops heat generation, determines whether the cover is closed using the open-close detector, controls the blower to blow air when the cover is closed, determines whether the recording medium is in the nip using the recording medium detector, controls the driver to rotate the two rotators when the cover is closed and no recording medium is in the nip, determines whether a temperature detected is equal to or lower than a threshold value before the cover is opened, and controls the blower to decrease an air volume when the temperature detected is equal to or lower than the threshold value.

摘要： A contact-separation device brings a contact-separation member into contact with a contacted member separably and includes a biasing member that generates a biasing force. A presser presses the contact-separation member against the contacted member in a pressing direction with the biasing force from the biasing member. A cam presses the presser in an opposite direction being opposite to the pressing direction. The cam is rotatable and has a cam face. A cam follower has a cam contact face that contacts the cam face of the cam. The cam contact face is curved to project toward the cam. The cam contact face has a curvature that is smaller than a greatest curvature of the cam face of the cam and is greater than a smallest curvature of the cam face of the cam.

摘要： Sensing of the pressing force of a balloon against internal body tissues is made possible using the balloon inserted into a gap in the body and pressing the internal body tissues around that gap without inserting a sensor, or the like, separately into the gap. A sensing system comprises an surgical assist manipulator provided to be able to travel by a reaction produced while it pressure-displaces the internal body tissues, a pressure sensor for measuring the pressure of fluid used to operate the surgical assist manipulator, and a pressing force measuring device for determining a pressing force applied to the internal body tissues by the surgical assist manipulator based on the measurement by the pressure sensor. The surgical assist manipulator includes a balloon which can be expanded/contracted by fluid being supplied internally, and the pressing force measuring device determines a function employing the internal pressure when the balloon is pressed as a parameter based on the measurement of fluid amount supplied to the balloon, and determines the pressing force by substituting the internal pressure at pressing measured by the pressure sensor into that function.
