A separation device includes an endless belt, a rotary body, a separation supporter, and a transfer mechanism. The separation supporter presses against an inner circumferential surface of the endless belt downstream from an area of contact between the endless belt and the rotary body in a recording medium conveyance direction to curve the endless belt toward an outer circumferential surface side of the endless belt at a greater curvature than a curvature of the endless belt at the area of contact between the endless belt and the rotary body. The transfer mechanism switches the separation supporter between a first position and a second position farther from the area of contact between the endless belt and the rotary body than the first position.

A fixing device includes a fixing rotator, a pressing rotator, an oil applicator, a first adjuster, a surface modifier, a second adjuster, and a processor. The fixing rotator contacts a recording medium bearing a toner image. The pressing rotator forms a fixing nip with the fixing rotator. The oil applicator is pressed against at least one of applied members of the fixing rotator and pressing rotator. The first adjuster adjusts contact/separation of the oil applicator with respect to the applied member. The surface modifier contacts the fixing rotator to modify a surface thereof. The second adjuster adjusts contact/separation of the surface modifier with respect to the fixing rotator. The processor allows the surface modifier to modify the fixing rotator surface after the oil applicator contacts the applied member, and the oil applicator to separate from the applied member after the surface modifier is separated from the fixing rotator.

A fixing device includes a rotary fuser member, a rotary pressure member, a first media stripper, and a second media stripper. The rotary fuser member is subjected to heating. The rotary pressure member is pressed against the fuser member to form a fixing nip therebetween through which a recording medium is passed in a media conveyance direction under heat and pressure as the fuser and pressure members rotate together. The first media stripper includes at least one pneumatic nozzle disposed adjacent to the fuser member to direct compressed gas toward the fixing nip along the fuser member for stripping the recording medium from the fuser member. The second media stripper includes at least one contact finger disposed in contact with the pressure member to slide against the pressure member during rotation for stripping the recording medium from the pressure member.
摘要:
A communication unit (32) periodically transmits a request signal toward a prescribed range. When a transmitter (30) exists in the range where the request signal can be received, it sends identification information in a responsive manner. A comparison ECU (48) compares the identification information provided from the communication unit (32) with a predetermined value, and if both of them match with each other, notifies a matching notification to a power source management ECU (44). On receipt of the matching notification from the comparison ECU (48), the power source management ECU (44) notifies a lighting-up request for providing an instruction for lighting-up of a light-emitting unit (202) to a body ECU (46). Upon receipt of the lighting-up request, the body ECU (46) activates a lighting-up command LON. As a result, the light-emitting unit (202) is lit up and notifies a user of the position of a charging port.

An image forming apparatus includes a charging unit, an image carrier, an exposing unit, a developing unit, a transfer belt on which the transfer material is placed, a fixing unit that fixes the toner image transferred onto the transfer material, a cleaning unit that cleans up toner attached to the fixing unit, and a control unit that controls printing of the image on the transfer material. The control unit causes the exposing unit to expose a latent image of a first image having an image-area ratio equal to or larger than a predetermined ratio, causes the developing unit to form a toner image of the latent image and to transfer the toner image to the transfer material, and causes the fixing unit to fix the toner image transferred by the transfer belt to the transfer material.

A fixing device fixes a toner image on a recording medium by heating the recording medium, with a heating area and a non-heating area selected in accordance with a magnetic flux and a repulsive magnetic flux. The fixing device includes a heat generating layer, an exciting coil, and a demagnetizing member. The heat generating layer generates heat. The exciting coil generates the magnetic flux, and thereby inductively heats the heat generating layer. The demagnetizing member faces the heat generating layer in the non-heating area. The demagnetizing member generates the repulsive magnetic flux against the magnetic flux generated by the exciting coil, and thereby demagnetizes the magnetic flux and suppresses the heating. Further, the demagnetizing member has a demagnetization effect different between at least a portion of the non-heating area adjacent to the heating area and the remaining portion of the non-heating area.

A fixing device includes a rotatable first nip formation member, a rotatable second nip formation member, and an oil applier. The second nip formation member is provided under the first nip formation member to contact the first nip formation member. The oil applier includes an oil pan, an oil receiver, and an oil filter. The oil pan is provided under the second nip formation member to contain oil in which the second nip formation member is dipped. The oil receiver holds the oil pan. The oil filter is provided between the oil pan and the oil receiver to filter oil overflowing the oil pan.

A fixing device includes a rotatable fixing member, a pressing member, a motor, and an oil applier. The pressing member contacts the fixing member. The oil applier includes an application roller and an oil supply mechanism. The application roller applies oil to one of the fixing member and the pressing member. The oil supply mechanism supplies oil to the application roller. The motor is provided independent of other drivers, and supplies a driving force to the application roller to rotate the application roller at an arbitrary speed.

A semiconductor light-emitting device and a method for manufacturing the same can include a wavelength converting layer located on at least one semiconductor light-emitting chip in order to emit various colored lights including white light. The semiconductor light-emitting device can include a base board, the chip mounted on the base board and a transparent plate disposed on the wavelength converting layer including a spacer and a phosphor having a high density. The wavelength converting layer can be formed in a thin uniform thickness between the transparent plate and a top surface of the chip using the spacer so as to extend toward the transparent plate. The semiconductor light-emitting device can be configured to improve light-emitting efficiency of the chip by using the thin wavelength converting layer including the phosphor having a high density, and therefore can emit a wavelength-converted light having a high light-emitting efficiency from a small light-emitting surface.
