摘要： A fixing device includes a pair of fixing members opposing each other and a pressing lever that is rotatable around a shaft. The pressing lever can be moved either to a pressing position in which one of the fixing members is pressed against the other fixing member, or to a pressure releasing position in which the one of the fixing member is separated from the other fixing member. When the pressing lever moves between the pressing position and the pressure releasing position, a first control unit located near an end of the pressing lever controls displacement of the end.

摘要： A neutralizing mechanism is provided on at least one conveying path proximal member installed on a conveying path of a sheet material in a vicinity of a transfer position, and is grounded by using a conducting material. The neutralizing mechanism includes a neutralizing circuit that includes a resistor and a ground switch electrically connected in parallel to each other. The ground switch is turned off at least at a time of applying the transfer bias to prevent a leakage of a transfer current, and turned on for a predetermined time at a time other than the time of applying the transfer bias to earth and remove a static electricity from the conveying path proximal member.

摘要： A fixing device includes a pair of first frames that support an axis of each of a fixing roller and a pressing roller and a pair of second frames arranged in parallel to an axial direction of the fixing roller to connect the first frames to each other. The second frames include cover portions that cover an upper peripheral surface and a lower peripheral surface of the rollers. A coupling member couples the cover portions to each other and has a bridge structure between the cover portions.

摘要： An image forming apparatus transfers a toner image on a recording medium in a transfer unit and fixes the toner image on the recording medium in a fixing unit. The image forming apparatus performs duplex image formation in a first mode and a second mode. The first mode is a mode in which a toner image is transferred and fixed on a second side of a recording medium after a toner image is transferred and fixed on a first side thereof. The second mode is a mode in which, after a toner image is transferred and fixed on a first side of a recording medium fed at first, a second side of the recording medium is subjected to fixing without transferring thereon a toner image.

摘要： A patch-pattern forming unit causes an image forming unit to form a patch pattern including a plurality of patches on a conveying member. A detecting unit detects the patch pattern formed on the conveying member. An adjusting unit adjusts an image forming condition of the image forming unit based on a result of detection by the detecting unit. The patch pattern has a length substantially equal to a distance between a patch-pattern start position, which is located at a space corresponding to at least a predetermined margin of a recording medium from a position of the image, and a position of the detecting unit.
