摘要： A roller support device includes a roller including a cylindrical portion having a through hole, a support member attached to a portion of an outer peripheral surface of the roller adjacent to the through hole to support the roller so that the roller is rotatable, and a restricting member including a bent hook and a contact portion. The restricting member restrains the support member from moving in a first direction of a rotation axis of the roller by contacting the support member at the contact portion. The bent hook is bent so as to extend to an inside of the cylindrical portion through the through hole and oppose a portion of the inner peripheral surface surrounding the through hole. The contact portion is disposed so as to extend in a circumferential direction of an outer peripheral surface of the roller and being capable of contacting the support member.

摘要： A fixing device includes a light source that emits laser light; a condensing member including a lens having a first surface from which the laser light enters and a second surface from which the laser light emerges, the lens condensing the laser light that has entered from the first surface and emitting the laser light from the second surface; and a roller provided in contact with the condensing member and that transports a recording medium advanced into a position between the roller and the condensing member. A portion of the second surface is made of a material that blocks the laser light. In a section perpendicular to an axis of rotation of the roller, a plane of contact between the roller and the condensing member includes at least a part of the portion made of the material that blocks the laser light.

摘要： A fixing device includes an endless belt member, a secured member disposed to contact the belt member, a heating unit that heats the belt member, and a rotary pressurizing roller including an elastic layer that is elastically deformed when the belt member is pressed against a pressing surface of the secured member to form a fixing part. The pressurizing roller is curved such that a center portion is smaller in outside diameter than end portions along the axial direction. The pressing surface is curved such that a center portion projects toward the pressurizing roller more than end portions along the longitudinal direction. On the pressing surface, an amount of projection of the center portion with respect to the end portions along the longitudinal direction is set to be larger on an output side than on an input side of the fixing part along a moving direction of the belt member.

摘要： A fixing device includes first to third support portions, first and second members, first and second biasing members, and a switching portion. The first support portion presses an endless belt against a rotating body. The second member is supported in the endless belt so as to be separable from the first support portion. The first biasing member biases the second member to a rotating body side. The second support portion supports the first support portion. The third support portion supports the second support portion, rotates the first support portion in a direction of approaching the rotating body by pressing the first support portion to the rotating body side at a first position, and is separated from the first support portion at a second position. The second biasing member biases the second support portion to the rotating body side. The switching portion switches between first and second states.

摘要： An image forming apparatus includes an image forming unit, a rotary member, a nipping area forming member, an assisting member, and a supporting unit. The image forming unit forms an image. The rotary member rotates while in contact with a recording medium, to which the image formed by the image forming unit is transferred. The nipping area forming member forms a nipping area for nipping the recording medium between the nipping area forming member and the rotary member. The assisting member assists the recording medium to peel off the rotary member, and forms a gap between the assisting member and the rotary member. The supporting unit supports the assisting member to be movable in a direction of separating from the rotary member and a transport path used to transport the recording medium.

摘要： A fixing device includes a light source that radiates a laser beam, a converging member that converges the laser beam, and a roller that is positioned so as to be in contact with the converging member and that transports a recording medium, which enters between the roller and the converging member. The converging member includes a lens that converges the laser beam, which is incident on a first surface of the lens, and emits the laser beam from a second surface of the lens and a holding member made of a material that does not transmit the laser beam, the holding member holding the lens. In the cross-sectional view perpendicular to a rotation axis of the roller, a contact surface in which the roller and the converging member are in contact with each other includes at least a portion of a surface of the holding member and the second surface.
