Abstract: An electro-photographic apparatus for conducting printing includes a fixing member fixing an unfixed toner image on a surface of a recording medium onto the recording medium. The fixing member includes a heating roller and a pressurizing member, and a mounting member on which the pressurizing member is mounted. The pressurizing member is supported by the mounting member in a substantially center part in a longitudinal direction of the pressurizing member.

Abstract: A fixing device includes a roller; an endless belt which is in contact with the roller and rotates with a circulation of the roller in a follower manner; a heating source in at lease one of an inside of the roller and an inside of the endless belt; and a pressure-applying member which is inside the endless belt and presses the endless belt against the roller. A sliding layer is provided on a side on which the pressure-applying member is in contact with the endless belt, and the sliding layer comprises at least two layers and holds a lubricant.

Abstract: A fixing unit that is provided in an image forming device and fixes a toner image transferred to paper is constructed of two belts, belt guides each of which guides the inner periphery of each of the belts, a heating member arranged in one of the belts or heating members arranged in both of the belts, a drive roller for driving the inner periphery of the belt, wherein the belts pinch paper on both surfaces thereof by the belt guides and carry the paper. This construction can realize a fixing unit reduced in size and capable of printing images at high speeds and shortening a rise time that elapses until the fixing unit reaches a fixable temperature.

Abstract: To accomplish high-speed fixing which requires high-precision temperature control, or fixing of high-quality color images on various kinds of paper without increasing the size and production cost of the temperature detecting means and contaminating the back sides of paper by toner that comes off from the temperature detecting element, an image for ming device is equipped with a fixing device comprising a heating roller, a pressing belt which forcibly contacts the heating roller, and a temperature detecting means which touches the surface of the heating roller to sense the surface temperature of the heating roller, wherein a cleaning means to clean the belt surface is provided on a place which is corresponding to a place at which the contact-type thermistor touches the heating roller.

Abstract: A fixing device comprising a first fixing means having a heating means disposed therein, a second fixing means, disposed to oppose to the first fixing means, for pinching a recording medium to form a first nip portion, a pair of transfer rollers, disposed at a downstream side of the recording medium, for forming a second nip portion, a guide for biasing the recording medium discharged from the transfer rollers towards the first fixing means side from one of the transfers, and means for biasing the guide towards the recording medium side.

Abstract: An image forming and recording apparatus, having a fixing apparatus for fixing unfixed toner image on a recording medium, wherein said fixing apparatus comprises: a fixing roller integrating a heater therein; an endless belt wound around said fixing roller; and three (3) pressure members for pressing said endless belt onto said fixing roller, wherein second one from a side of entry of paper is made at maximum in pressure loading, among said three (3) pressure members, thereby achieving stable fixing of oil-less toner at high speed.

Abstract: An image forming device and method utilizing an electrostatic latent image recording medium, developing units reserving different colors for developing images on the recording medium, a dryer for drying the developed images, and an adhesion reinforcer for enhancing adhesion of toner particles including electrostatically pressing dried toner particles against a front surface of the electrostatic latent image recording medium.

Abstract: A fixing device in an image formation apparatus has a heating roller and a backup roller. These rollers are each coated with single silicone rubber layers around the respective peripheries of their core bars. This silicone rubber has a volume resistance value of 1013 &OHgr;·cm or more. The heating roller is charged with electricity of the same polarity as the polarity of toner particles due to frictional electrification caused at the time of feeding of a recording medium. The heating and the backup roller are polarized reverse to the polarity of the recording medium. A quantity of charged electricity on the backup roller is made larger than that on the heating roller. This permits the image formation apparatus to prevent offset from occurring at the time of fixing a toner image onto the recording medium to cope with various types of recording media.

Abstract: An actuator for driving a driven member which comprises a base, first and second driving members each fixed to the base and having one vibrating direction, a resultant motion mechanism connected to the first and second driving members, combining their unidirectional vibrations and generating resultant vibration having circular orbit, a driving element transmitting the resultant motion of the resultant motion mechanism to the driven member, and a device for imparting excitation force to the first and second driving members.
