Abstract: An image forming apparatus includes a fixing portion, a sheet conveying portion, a first airflow generating portion, a setting processing portion, and a first drive processing portion. The fixing portion heats a sheet on which a toner image has been transferred to fix the toner image to the sheet. The sheet conveying portion conveys a sheet along a conveyance path that leads to a sheet discharge port via the fixing portion. The first airflow generating portion includes a first fan and generates an airflow flowing upstream from the fixing portion in a conveyance direction of the sheet. The setting processing portion sets a drive speed of the first fan based on either or both of a sheet size, and a conveyance interval at which the sheet conveying portion conveys the sheet. The first drive processing portion drives the first fan at the drive speed set by the setting processing portion.

Abstract: A developing device includes a developing roller and a developing magnetic pole. The developing roller is disposed to face an image carrier across a predetermined gap. The developing magnetic pole is provided in the developing roller so as to be displaced between first and second magnetic pole positions. When the developing magnetic pole is at the first magnetic pole position, a magnetic field is generated at a first position in the gap. When the developing magnetic pole is at the second magnetic pole position, a magnetic field is generated at a second position in the gap. When a circumferential speed ratio of the developing roller to the image carrier is increased, the developing magnetic pole is displaced toward the second magnetic pole position, and when the circumferential speed ratio is decreased, the developing magnetic pole is displaced toward the first magnetic pole position.

Abstract: A fixing device includes a fixing member, a pressuring member, a separation member and a bearing. The fixing member is heated by a heat source. The pressuring member is brought into pressure contact with the fixing member to form a fixing nip with the fixing member. The separation member has a main body part and a shaft part projecting in an axial direction from the main body part to become the rotation center, and is configured so that one end of the main body part come into contact with the fixing member. The bearing pivotally supports the shaft part of the separation member. The bearing is formed so that its contact portion coming into contact with the shaft part has shorter width in the axial direction than other portion.

Abstract: An electricity removing unit 50 includes a rotating roller part 51, a brush part 52, a driving part, and a restraint member. The brush part 52 includes a plurality of conductive fiber bristles 52a having base end portions connected to a peripheral surface of the rotating roller part 51. The driving part rotationally drives the rotating roller part 51. The restraint member abuts the brush part 52 from a rotation downstream side, thereby inclining the plurality of conductive fiber bristles 52a to an upstream side from a downstream side of a rotational direction toward a radial outside and thus reforming them. In this way, the restraint member restrains a distance between a front end of each conductive fiber bristle 52a and the peripheral surface of the rotating roller part 51 to a setting distance set in advance.

Abstract: Three links within one width-direction unit are included in respectively different link units. The links in the first row and the sixth row from the right end and the left end of a chain are included in the same link unit. The links in the second row and the fifth row are included in the same link unit. The links in the ninth row and the tenth row are included in the same link unit other than the link unit in which the links in the second row and the fifth row are included. With the above structure, the stress amplitude of the links forming a chain for a chain-type continuously variable transmission can be reduced.
