Abstract: A fusing device includes a first roller, a second roller forming a fusing nip part together with the first roller, an adjustment mechanism changing posture of the first roller between first and second postures, a separation member, a turning mechanism, an abutting member, and an isolation mechanism. The turning mechanism turns the separation member so that the separation member approaches the first roller when the posture of the first roller is changed from the second posture to the first posture. The abutting member abuts on the first roller to form a gap between the separation member and the first roller when the first roller is in the first posture. The isolation mechanism separates the abutting member from the first roller in a process when posture of the first roller is changed from the first posture to the second posture.

Abstract: A gripping method is for gripping an object using a gripping mechanism including a roller and a frame that houses the roller. The gripping method includes a first stage and a second stage. In the first stage, the gripping mechanism moves relative to the object such that a first portion of the object is gripped between an outer surface of the roller and an inner surface of the frame. In the second stage, the gripping mechanism further moves relative to the object such that the roller is lifted by a second portion of the object before gripping of the object is released.

Abstract: A fixing device includes a cylindrical fixing member, a pressing member, a bearing and a heat insulating member. The fixing member is heated by a heat source. The pressing member forms a fixing nip between the pressing member and the fixing member. The bearing supports an end portion of the fixing member in a rotatable manner. The heat insulating member is interposed between the bearing and the end portion of the fixing member. The heat insulating member has a cylindrical part and a flange part. The cylindrical part has a slitting groove extending along an axis direction of the cylindrical part. The flange part extends outward in a radial direction of the cylindrical part from one end of the cylindrical part in the axis direction. At least one notch is formed along an outer circumferential edge of the flange part.

Abstract: A fixing device includes a fixing member, a pressing member and a separating member. The fixing member is provided with a sheet passing region through which a recording medium is passed and a non-sheet passing region arranged outside the sheet passing region. The pressing member comes in pressure-contact with the fixing member to form a fixing nip. The separating member is configured to separate the recording medium passed through the fixing nip from the fixing member. The separating member has a separating plate and a restricting piece. The separating plate faces the sheet passing region with an interval. The restricting piece restricts the interval. The restricting piece is provided with a contacting surface which comes in contact with the non-sheet passing region. The contacting surface has a width which becomes wider from an upstream side to a downstream side in the rotation direction of the fixing member.

Abstract: A fixing device includes a first rotary member, a second rotary member, a support member having a connection part, an urging member, and an engaging member. The engaging member is capable of changing a state of the fixing device between a pressure applied state and a pressure reduced state using the urging member and the support member. When the nip pressure is in the pressure applied state, the engaging member changes a position of the urging member to direct the urging member longitudinally in a tangential direction to an arc that has a center coinciding with a center of rotation of the support member and that passes through the connecting portion. When the nip pressure is in the pressure reduced state, the engaging member changes the position of the urging member to direct the urging member longitudinally in a direction different from the tangential direction.
