摘要:
A low-friction sliding material comprising a sliding member having a sliding surface, and a fluorine fiber or a fluorine fiber-containing composite fiber that is disposed in parallel at least on the outermost part of the sliding surface in a direction substantially the same as a sliding direction and covers 60% or more of the sliding surface. The present invention provides a low-friction sliding material that is free from the occurrence of fabric separation or other defects in an extremely easy manner as compared to the conventional art.

An image forming apparatus (1) includes a first toner image forming unit (30E) for forming first toner image on a transfer belt (15) with a first toner and a second toner image forming unit (30K) for forming a second toner image on the transfer belt (15) with a second toner. A secondary transfer unit (23) transfers the first and second toner images from the transfer belt (15) to a sheet (P) traveling in a sheet transport direction. A fixing unit (17) fixes the first and second toner images to the sheet. A control unit (50) controls the first toner image forming unit (30E) to form a first pattern (TPe), the second toner image forming unit to form a second pattern (TPk), and to leave a margin (M) on a downstream side of the sheet (P) in the sheet transport direction that is greater than or equal to a circumferential distance of a fixing element (300) in the fixing unit (17).
摘要:
An image forming apparatus (1) is disclosed, including: a toner image forming unit which forms a toner image on a surface of a transfer material, the toner image being an image formed of toner, the toner containing wax; a fixing device (25) which fixes the toner image using a fixing member on which a mold release agent including oil is applied; and a surface processing device (70) which processes the fixed surface of the transfer material, on which surface the toner image is fixed using the fixing member on which the mold release agent including the oil is applied, wherein the surface processing device (70) further includes a discharging unit which generates a discharge on or near the fixed surface of the transfer material, on which surface the fixed toner image is formed.

The present invention is a release oil of the general formulae: wherein (Z) is an amine. The solvent extracted portion of the release oil has a ratio of A:B less than 1:5. Less than 10% of the molecular weight distribution of the release oil is less than m/z 1000. The release oil preferably has a viscosity of between 200 and 500 centistokes.
摘要:
A printing apparatus (103) which is capable of preventing printing from being performed on a sheet different from a sheet originally intended for printing, after completion of cleaning. The printing apparatus has a fixing device (751) for fixing an image recorded on a sheet fed from a sheet feeder. The printing apparatus feeds a sheet from the sheet feeder and performs cleaning of the fixing device using the fed sheet. After execution of the cleaning of the fixing device, the printing apparatus requests a user to set a sheet to be used for a page to be printed next, in the sheet feeder.

An image heating apparatus includes first and second rotatable members configured to form a nip for heating a toner image on a sheet; a rotatable rubbing member configured to rub an outer surface of the first rotatable member; and a contact-and-separation mechanism configured to move the rotatable rubbing member toward and away from the first rotatable member. When the contact-and-separation mechanism executes a rubbing process, the contact-and-separation mechanism repeatedly executes alternately a first process for contacting the rotatable rubbing member with the first rotatable member and a second process for spacing the rotatable rubbing member from the first rotatable member.

A fixing device (80) includes an endless, rotary fixing member (81); a heat source to heat the fixing member (81); an opposed member (82) disposed opposite the fixing member (81) and to form a fixing nip (84) with the fixing member (81); and a biasing member (83) disposed opposite the opposed member (82), to press the fixing member (81) from a back side of the fixing member (81) against the opposed member (82) at the fixing nip (84); grip portions (G1, G2) at which the fixing member (81) and the opposed member (82) contact each other in areas through which the recording medium (S) does not pass, among the fixing nip (84) along a direction perpendicular to a conveyance direction of the recording medium (S); and a cleaning member (86, 87) to clean one of the grip portions (G1, G2) of the fixing member (81) and the opposed member (82).
摘要:
A belt fuser assembly which dispenses lubricant oil or other depleted lubricant component to the inner surface of the fuser belt. The belt fuser assembly may include a lubricant dispenser positioned to be heated by the heating element of the fuser assembly for dispensing a lubricant oil to the inner surface of the fuser belt. The lubricant dispenser may include a reservoir containing the lubricant oil and an exit port for delivering the lubricant oil from the reservoir to the inner surface of the fuser belt upon the reservoir being heated by the heating element at a temperature above the fusing temperature of the belt fuser assembly.
