  • Patent number: 11336786
    Abstract: A sheet discharging apparatus includes a first stacking unit to stack a sheet discharged by a first discharge unit, a second stacking unit disposed below the first stacking unit to stack the sheet discharged by a second discharge unit, and a lifting unit to lift and lower the first and second stacking units. A detection unit changes an output value based on contact of a matter with a lower surface of the first stacking unit, and a distance estimation unit estimates a distance between the first stacking unit and the second stacking unit. A separation process lifts the first stacking unit to increase a distance between the first and second stacking units in a vertical direction in a case where the output value changes based on contact of the matter with the lower surface of the first stacking unit and the estimated distance being smaller than a threshold value.

  • Patent number: 10571844
    Abstract: An image forming apparatus includes an image forming portion configured to form an image on a recording material, and a fixing portion including a first rotatable member and a second rotatable member, rotatable by rotation of the first rotatable member, and in contact with the first rotatable member. The fixing portion fixes the image on the recording material by heating the image while nipping and feeding the recording material, on which the image is formed, at a nip formed between the first rotatable member and the second rotatable member. A motor drives the first rotatable member, and torque detecting means detects a driving torque of the motor. On the basis of the driving torque detected by the torque detecting means, a controller controls a degree of temperature rise of the first rotatable member immediately before the recording material enters the nip.
