摘要： PROBLEM TO BE SOLVED: To provide a fixing unit in which a fixing roller is not damaged and which improves print quality.
SOLUTION: The fixing unit 1 which fixes a toner image by heating and pressuring a medium where the toner image is transferred by a fixing roller 6 and a pressure roller 7 has a separator plate 11 arranged nearby the fixing roller 6 to nearly the overall length of the fixing roller 6 and is provided with a separator plate 14 nearby the pressure roller 7 to nearly the overall length of the pressure roller 7. The separator plate 11 does not come into contact with the fixing roller 6 and the gap between the separator plate 11 and the fixing roller 6 is set shorter than the distance by which a front end of paper leaves the fixing roller 6. The front end of the paper is a little apart from the surface of the fixing roller 6 and a tip portion of the separator plate 11 enters the gap to separate the paper from the fixing roller.

摘要： PROBLEM TO BE SOLVED: To provide a fixing device capable of preventing the deterioration of quality of a printed matter.SOLUTION: The fixing device comprises: a fixing member; a pressure member disposed opposite to the fixing member; and a separation member for separating a medium passed through a fixing part which is formed between the fixing member and the pressure member from either of the fixing member or the pressure member and guiding the medium to an exhaust port of a case. A heat capacity reducing area for reducing a heat capacity is formed in the separation member, and therefore a temperature of a paper passing surface facing the conveyed medium of the separation member can be raised rapidly. As a result, water drops can be prevented from attaching to the medium and adhesion of dirt to the medium, an occurrence of wrinkles in the medium, and image disturbance are prevented.

摘要： PROBLEM TO BE SOLVED: To provide an inexpensive fixing apparatus having high reliability. SOLUTION: The fixing apparatus includes a heating member heating a developer image; an endless belt holding a recording medium between it and the heating member and traveling so that the recording medium is conveyed, when the heating member is driven and rotated; a pressure roller provided inside the endless belt and rotated while pressing the endless belt against the heating member; a pressure pad arranged side by side with the pressure roller inside the endless belt, including a pressure surface having elasticity and in press contact with the endless belt, and pressing the endless belt against the heating member; and a belt guide member guiding the inner surface of the endless belt, while loosely holding it at the inside of the endless belt. The pressure surface is obtained by adding a solid lubricant that is one among graphite, tetrafluoro-ethylene, powder of polytetrafluoro-ethylene or molybdenum disulfide to an elastic base material in which at least epoxy denatured silicone or amino silane is added to a silicone rubber material.

摘要： PROBLEM TO BE SOLVED: To prevent insufficient fixing and to improve image quality. SOLUTION: The fixing device controller includes a first fixing part heated by a heating body, a second fixing part disposed to abut against the first fixing part, a frame to surround the first and the second fixing parts, a frame temperature detection part to detect the temperature of the frame and a control part, to control the heating body so as to control the temperature of the first fixing part. Since the control part sets set temperature showing a target value of the temperature of the first fixing part, based on the temperature of the frame detected by the frame temperature detecting part, temperature difference between the center parts and the edges of the first and the second fixing parts is prevented from occurring.

SOLUTION: The fixing device includes: a fixing means which comes into press-contact with a conveyed recording medium, to fix a developer on the recording medium; a plate which supports the fixing means; a guide means which guides the recording medium on which the developer is fixed, so as to separate the recording medium from the fixing means; a spacer means which is rotatable around a post formed in the plate and determines the gap; and an energizing means which is disposed around the post and energizes the spacer means so as to bring it into contact with the fixing means. The top end portion facing the fixing means of the guide means is located within the range of the contact area of the spacer means with the fixing means in the rotational direction of the fixing means.

摘要： PROBLEM TO BE SOLVED: To increase image quality by preventing a friction mark from being formed vividly on the surface of a fixing member.
SOLUTION: The fixing device has a pressure member, the fixing member movably disposed to be opposed to the pressure member, and an abutting element disposed to abut on the circumferential surface of the fixing member. The surface roughness of the fixing member is set to 1.0 to 4.0 (μm). In such a case, when the fixing member is moved in a state where the abutting element abuts on the fixing member, the surface of the fixing member is rubbed by the abutting element, but the surface roughness of a part with which the abutting element comes into contact and that of a part with which it does not come into contact are nearly equal to each other, because the surface roughness of the fixing member is set to 1.0 to 4.0 (μm).
