Abstract: A moving body includes a housing, a traction motor, a plurality of elevator motors and a battery. The traction motor allows the housing to travel along a traveling surface. The plurality of elevator motors actuates an elevator unit, the elevator unit being configured to be elevated and lowered with respect to the traveling surface. The battery supplies electric power to the traction motor and the plurality of elevator motors. In the moving body, the plurality of elevator motors, the traction motor, and the battery are distributed when viewed perpendicularly to the traveling surface. The moving body further comprises at least one driving wheel to support the housing on the traveling surface. The plurality of elevator motors, the traction motor, and the battery fall, in a direction perpendicular to the traveling surface, within a range defined by a diameter of the at least one driving wheel.

Abstract: An image forming apparatus includes a fuser unit which includes a heat roller and a pressure roller; a duct which is formed in a long shape in a direction along an axis of the heat roller, is disposed in the vicinity of the fuser unit along the axis of the heat roller, and is exhausted by an exhaust fan which is provided on one end side in a long-side direction; an exhaust port which is opened to a first side wall of the fuser unit side of the duct and causes the fuser unit and the duct to communicate with each other; and a planar filter which is attached to an inner wall surface of the duct. The filter includes a filter base material having an irregular surface shape in which ditches and convex portions are alternately disposed; and a frame which is bonded to both ends orthogonal to an irregularity direction of the filter base material, the convex portion of the filter base material protrudes from the frame, and the convex portion of the filter base material is bonded or stuck to the inner wall surface.

Abstract: Disclosed is an image forming apparatus including: an ejection section including an ejection roller to eject a sheet from a first sheet passing path to a sheet ejection port and a reverse roller to reverse a transport direction of a sheet transported along a second sheet passing path, the ejection roller and the reverse roller being placed close to each other and close to the sheet ejection port; and a switching lever switches the transport destination of the sheet between the first and the second sheet passing paths for transporting the sheet to the ejection roller and to the reverse roller, respectively. A moving trajectory of a sheet transported along the first sheet passing path between the ejection roller and the switching lever is substantially identical to a moving trajectory of a sheet transported along the second sheet passing path between the reverse roller and the switching lever.

Abstract: Disclosed is an image forming apparatus that forms an image on one side of a sheet and then forms an image on the other side of the sheet. A single-sided sheet passing path transports a sheet housed in a sheet-feeding tray to the image forming section, and a double-sided sheet passing path reverses a sheet with an image formed on one side and causes the sheet to join the single-sided sheet passing path. The single-sided sheet passing path is formed so as to include a second interval which includes a registration sensor placed near a joining position of the single-sided and double-sided sheet passing paths in the double-sided sheet passing path as one end point and in which a sheet draws a moving trajectory substantially identical to a moving trajectory of a sheet in a first interval extending toward an upstream side in the transport direction of the sheet.

Abstract: An image forming apparatus includes an image forming mechanism to form a toner image on a recording medium according to image data and a fixing mechanism to fix the toner image on the recording medium. The fixing mechanism includes a fixing member and an external heater. The fixing member applies heat to the recording medium having the toner image. The external heater heats the fixing member and is formed in a shape corresponding to a surface of the fixing member. The external heater is disposed as if to engage and yet be spaced apart from the fixing member by a distance which is variable according to movement of the external heater.
