Abstract: A gripping mechanism includes an inclined surface, a rolling element, and a facing gripping part. The inclined surface is a surface inclined to a vertical direction. The rolling element freely rolls obliquely upward and downward on the inclined surface. The facing gripping part is arranged to face the inclined surface and forms an opening space with an end of the inclined surface, the opening space being narrower than a diameter of the rolling element. The rolling element includes: a core member forming a core of the rolling element; an annular member that is provided around the core member and has elasticity; and a plurality of ribs each of which is interposed between an outer periphery of the core member and an inner periphery of the annular member, and forms a gap between the core member and the annular member.

Abstract: A fixing device fixes a toner to a recording medium. The fixing device includes a rotary member, a bearing, and a bearing holder. The rotary member is rotatable about an axis of rotation of the rotary member. The bearing is disposed around an end part of the rotary member. The bearing holder holds the bearing. The bearing has an outer circumferential surface with a flat portion and a bearing groove. The bearing groove has a bottom surface, a first side surface, and a second side surface. The first side surface of the bearing groove is capable of being in contact with the bearing holder. The second side surface of the bearing groove is capable of being in contact with the bearing holder. The bearing holder is engaged with the bearing groove such as to be in contact with the first and second side surfaces of the bearing groove.

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 and a non-sheet passing region. The separating member has a separating plate and a restricting piece. The restricting piece is provided with a curving surface on a region including the contacting portion with the non-sheet passing region. The curving surface has a first curving area and a second curving area. The first curving area is provided on a downstream side from the contacting portion in a rotating direction of the fixing member. The second curving area is provided on an upstream side from the contacting portion in the rotating direction of the fixing member. The second curving area has a radius of curvature larger than that of the first curving area.
