An image forming apparatus includes an image forming device, a fixing device including a first rotary member of which a surface layer containing a fluororesin is brought into contact with a sheet surface having an unfixed toner image formed by the image forming device, and a controller. In a case that image formation processing for continuously forming a toner image on a plurality of predetermined sheets is executed, the controller can control conveyance of a sheet so that a portion of the surface layer of the first rotary member which is brought into contact with a trailing edge of a preceding sheet is brought into contact with a margin area on a leading edge side on a next sheet.

Image forming apparatus and cleaning method

An image forming apparatus includes an image forming device that forms a toner image on a recording medium, a first rotator, and a second rotator that presses against the first rotator to form a nip therebetween. The first rotator conveys the recording medium bearing the toner image through the nip with a first orientation of the recording medium to fix the toner image on the recording medium to create a cleaning sheet bearing a cleaning image in a cleaning sheet creation mode. The first rotator conveys the cleaning sheet bearing the cleaning image through the nip with a second orientation of the cleaning sheet, that is different from the first orientation of the recording medium, such that the cleaning image is disposed opposite the first rotator to cause the cleaning image to remove a foreign substance from a surface of the first rotator in a cleaning mode.

CONSTANT LUBRICANT APPLICATION

An example lubricant applying device includes a rotatable applicator, a solid lubricant source to supply lubricant to the applicator, an urging member to urge the lubricant source to contact the applicator, and a guide member to restrict an urging of the lubricant source along a displacement direction. In a transverse cross section of the lubricant applying device that is taken orthogonally to a rotation axis of the applicator, a reference line extends from a contact surface of the lubricant source to the rotation axis of the applicator, in a direction parallel to the displacement direction of the guide member. In the transverse cross section, the lubricant source has a width that is substantially orthogonal to the displacement direction. The lubricant source is positioned to offset a widthwise center of the lubricant source to a downstream side of the reference line, in the rotational direction of the applicator.

A fixing device fixes a toner image to a medium conveyed in a conveying direction, the toner image formed on the medium, the fixing device including a heating rotating body, a heater, a pressing member, a pressing rotating body, and a lubricant holding member. The heater heats the heating rotating body, which is supported to be rotatable. The pressing member is disposed inside the heating rotating body. The pressing rotating body is pressed against the pressing member through the heating rotating body to form a nip through which the medium passes. The lubricant holding member has an abutting surface that abuts against an inner circumferential surface of the heating rotating body, and the abutting surface includes a first region filled with a first lubricant and a second region filled with a second lubricant.

IMAGING SYSTEM

An imaging system includes a main body to accommodate a roller, and a lubricant unit. The lubricant unit includes a casing having an opening and a lubricant storage disposed inside the casing to store a lubricant. The casing is pivotably connected to the main body to displace the casing between a closed position and an open position. In the closed position, the lubricant storage is positioned to bring the lubricant in contact with the roller through the opening, and the pivotable connection is disposed below the casing. In the open position, the opening is exposed to an outside of the main body, and the opening of the casing is disposed upward.

An image forming apparatus includes: a lubricant supplier that supplies a lubricant onto an image carrier; a fixing member that is rotatable, and comes into contact with the image carrier to fix the lubricant supplied onto the image carrier; and a hardware processor that controls rotation of the fixing member.

System and method for applying lubricant onto a surface

A system and method for applying lubricant to a surface, such as a heating surface of a fuser member. The system includes lubricant conduit for carrying pressurized lubricant toward a spraying assembly. A heating element surrounds the lubricant conduit and heats the pressurized lubricant before it arrives at the spraying assembly. The system also includes a pair of double O-ring sealing assemblies for sealingly coupling a lubricant tube to the system.

HEATING DEVICE AND IMAGE PROCESSING DEVICE

A heating device includes a cylindrical body with a hollow interior and a heater inside the hollow interior. A first surface of the heater faces the inner surface of the cylindrical body. A heat transfer member is on a second surface of the heater. A grease is between the heater and the heat transfer member. A support member is provided including a first portion fixed to the second surface of the heater and a second portion contacting a surface of the heat transfer member. The support member includes a third portion between the first and second portions. The third portion does not contact the second surface of the heater between the first and second portions and provides a space for grease from between the heater and the heat transfer member to accumulate.
