    摘要: A fixing device includes a guide disposed downstream from a fixing nip formed between a fixing rotator and a pressure rotator, through which a recording medium is conveyed. A pressure rotator side separator, disposed downstream from the fixing nip in a recording medium conveyance direction, includes an opposed tip disposed opposite an outer circumferential surface of the pressure rotator and a separation-conveyance face that separates the recording medium from the pressure rotator. The opposed tip and the separation-conveyance face define a hypothetical circle having a curvature not smaller than 1/20 that intersects a guide face of the guide at an intersection at which a hypothetical tangent is tangent to the hypothetical circle. The hypothetical tangent and the guide face define a downstream intersection angle that is downstream from the hypothetical tangent in the recording medium conveyance direction and is greater than 90 degrees.

    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 an endless fixing belt stretched taut across a first roller and a second roller and rotatable in a predetermined direction of rotation. A pressure rotator is pressed against the first roller via the fixing belt to form a fixing nip between the pressure rotator and the fixing belt, through which a recording medium is conveyed. A separation aid, disposed downstream from the fixing nip in the direction of rotation of the fixing belt to separate the recording medium from the fixing belt, includes a contact face contacting an inner circumferential surface of the fixing belt and a bulge disposed at a center of the contact face in a longitudinal direction of the separation aid. The bulge projects toward the inner circumferential surface of the fixing belt relative to each lateral end of the contact face in the longitudinal direction of the separation aid.

    摘要: An image forming apparatus includes an oil input device and a fixing device including a fixing member, a pressing member, and an oil applier. In the oil applier, an oil application member applies oil supplied from an oil supply mechanism to one of the fixing member and the pressing member. In the oil supply mechanism, an oil supply member provided adjacent to an oil storage member supplies oil sent from the oil storage member to the oil application member. When the fixing device is reattached to the image forming apparatus after the fixing device is detached from the image forming apparatus, oil sent from the oil input device through an oil inlet overflows the oil storage member, and is supplied to one of the oil supply member and the oil application member provided adjacent to the oil storage member before an image forming operation starts.
