摘要： A sheet feeder, which is incorporated in an image forming apparatus, includes an attraction body disposed facing a bundle of sheets, a charger to charge the attraction body to electrostatically attract an uppermost sheet of the bundle of sheets to the attraction body, a liquid supplier to supply a liquid to dissolve discharge products to the attraction body, and a liquid remover to remove the liquid from the attraction body. Further, a method of removing discharge products includes counting the number of sheets fed from a sheet container, determining that the number of sheets reaches a predetermined threshold value, confirming that a current time falls within a predetermined period of time or receiving a turn off signal to turn off a power supply, removing the discharge products from a surface of an attraction body, and resetting the number of sheets or further turning off the power supply.

摘要： An image forming apparatus includes a sheet container accommodating a recording medium therein, a sheet separating feeder including a sheet feeding body and a sheet separating body, an image forming part, and a bend applier. The sheet feeding body feeds the recording medium along with a surface movement thereof while the recording medium contacting the surface thereof. The sheet separating body forms a sheet separation nip region with the sheet feeding body and sandwiches the recording medium in the sheet separation nip region. The sheet separating feeder separates and feeds the recording medium contacting the sheet feeding body. The image forming part forms an image on the recording medium. The bend applier having a leading end of an elastic material contacts and bends the recording medium before the sheet separation nip region and generates a wrinkle extending on the recording medium in a sheet conveying direction.

摘要： A vacuum pump includes a casing having an inlet port and an outlet port, a stator portion provided inside the casing and a rotor portion having a shaft rotatably supported inside the casing and a rotor disposed on the shaft and provided with a gas transfer mechanism that transfers a gas from the inlet port to the outlet port. The rotor portion is arranged with a predetermined clearance between the rotor portion and the stator portion. A motor rotates the shaft. Vibration detection disposed in the stator portion detects vibrations by converting vibration amplitude to an electric signal. Contact detection judges an occurrence of contact between the stator portion and the rotor portion when, in the vibration detected by the vibration detection, an amplitude in frequency of a specific vibration caused by contact between the stator portion and the rotor portion exceeds a predetermined threshold value.
