摘要： A fixing device includes a fixing member, a pressure member, a separation member and a separation/contact mechanism. The fixing member and the pressure member are provided so as to separate away from or come in contact with each other and to form a fixing nip. The fixing member has a flexibility and is deformable by separating away from or coming in contact with the pressure member. The separation member is disposed to face the fixing member and configured to separate a sheet passed through the fixing nip from the fixing member. The separation/contact mechanism is configured to support the separation member such that a fixing member side edge portion of the separation member is deformed along the fixing member in synchronization with the separating and contacting of the fixing member and the pressure member.

摘要： A fixing device includes a first roller contacting a fixing belt to generate a rotation friction force therebetween to rotate the fixing belt and a second roller contacting the fixing belt to exert a first inhibition force to the fixing belt in a direction opposite a direction of rotation of the fixing belt. A separation aid is disposed downstream from a fixing nip formed between the fixing belt and a pressure rotator in the direction of rotation of the fixing belt to decrease a curvature of the fixing belt and exert a second inhibition force to the fixing belt in the direction opposite the direction of rotation of the fixing belt. The second inhibition force is added to the first inhibition force to obtain a combined inhibition force that is smaller than the rotation friction force between the fixing belt and the first roller.

摘要： A fixing device includes a fixing belt stretched taut across a fixing rotator and a support rotator. A pressure rotator is pressed against the fixing rotator via the fixing belt to form a fixing nip between the fixing belt and the pressure rotator, through which a recording medium bearing a toner image is conveyed. The pressure rotator includes a recess defining an outer diameter of each lateral end of the pressure rotator in an axial direction thereof that is greater than an outer diameter of a center of the pressure rotator in the axial direction thereof. A first separator is disposed downstream from the fixing nip in a recording medium conveyance direction and contacts an inner circumferential surface of the fixing belt. The first separator is isolated from the pressure rotator and includes a projection disposed opposite the recess of the pressure rotator.
