Abstract: An image forming apparatus includes a conveyance unit configured to convey a sheet, a measurement unit for measuring a feature amount of the sheet conveyed by the conveyance unit, a sheet detection sensor for detecting the sheet conveyed by the conveyance unit, a pressing member movable between a first position separated from the measurement unit and a second position closer to the measurement unit than the first position, a moving unit configured to move the pressing member, an image forming unit configured to form, based on a predetermined image forming condition, an image on the sheet conveyed by the conveyance unit, and a controller, the controller is configured to stop conveyance of the sheet by the conveyance unit in a case where the sheet is detected by the sheet detection sensor.

Abstract: A sealing member and an air intake controller are disclosed herein. The sealing member includes an inner cylindrical section having a gradually-decreasing-diameter portion which has a diameter that gradually decreases in one direction, an outer cylindrical section having a gradually-increasing-diameter portion which has a diameter that gradually increases in the one direction, and an annular connecting section which connects the inner cylindrical section and the outer cylindrical section at an end portion on the side in the opposite direction from the one direction. The outer cylindrical section has an extended cylindrical portion, the outer diameter of which gradually decreases in the one direction. An air intake controller can incorporate the sealing member that is disclosed herein between a shaft hole 1 and a valve shaft.

Abstract: The present invention provides a sealing member and an air intake controller. A sealing member 1 includes an inner cylindrical section 3 having a gradually-decreasing-diameter portion 2 which has a diameter that gradually decreases in one direction, an outer cylindrical section 5 having a gradually-increasing-diameter portion 4 which has a diameter that gradually increases in the one direction, and an annular connecting section 6 which connects the inner cylindrical section 3 and the outer cylindrical section 5 at an end portion on the side in the opposite direction from the one direction. The outer cylindrical section 5 has an extended cylindrical portion 7, the outer diameter of which gradually decreases in the one direction. An air intake controller 11 has the sealing member 1 between a shaft hole 15a and a valve shaft 8a.
