The conveying path is provided in the intermediate collection box. The conveying screw is rotatable in the conveying path. Through the exhaust path, air containing a floating toner is sucked and passed. The floating toner collection chamber is provided on a part of the exhaust path in the intermediate collection box. The floating toner collection chamber has a discharge opening opened to an inside of the intermediate collection box and a discharge door. Rotation of the conveying screw in a normal direction turns the discharge door into a storage position where the discharge opening is closed. Rotation of the conveying screw in a reverse direction turns the discharge door into a discharge position where the discharge opening is opened.

Abstract: A waste toner transporting device includes a waste toner passing passage, a waste toner collection container, a suction passage, a suction device, and a passing passage box. Through the waste toner passing passage, waste toner passes. The waste toner collection container collects the waste toner having passed through the waste toner passing passage. In the suction passage, suspended toner is sucked along with air inside a developing device. The suction device sucks the air inside the suction passage. Inside the passing passage box, the waste toner passing passage constituting part of the waste toner passing passage is formed. The suction passage constituting part of the suction passage is formed inside the passing passage box so as to be connected to the waste toner passing passage.

Abstract: A fixing device includes a rotating member, a bearing and a heat insulating member. The rotating member fixes a toner image onto a recording medium. The bearing rotatably supports the rotating member. The heat insulating member is interposed between the rotating member and the bearing and rotated around a rotation axis. A notch part is arranged in a portion in a circumferential direction of the heat insulating member so as to continue from an end part at an inside to an end part at an outside in a direction of the rotation axis. At least one groove part is formed in a contact portion with the rotating member or the bearing in a circumference face of the heat insulating member.

Abstract: A cleaning device includes a cleaning roller, a bearing member, a guiding member and an energizing member. The cleaning roller includes a second gear meshed with a first gear of an image carrier. The cleaning roller is rotationally driven in an opposite direction to the image carrier by driving force transmitted from the first gear to the second gear. The bearing member supports a core metal of the cleaning roller. The guiding member has a placement face on which the bearing member is placed. The placement face is inclined with regard to a straight line passing through a rotation center of the first gear and a rotation center of the second gear so that a distance between the straight line and the placement face becomes larger, the closer to the first gear. The energizing member energizes the bearing member so as to press the cleaning roller to the image carrier.
