  • Patent number: 10928760
    Abstract: An image forming apparatus includes an image forming portion configured to form a toner image on a recording material; a fixing portion configured to fix the toner image on the recording material by heating the toner image formed on the recording material; a flow path including a first space connecting with the fixing portion and a second space connecting with the first space and through which air discharged from the fixing portion passes; a first electrode portion provided in the first space and provided with a first potential; and a second electrode portion provided in the second space and provided with a second potential different from the first potential. An air speed of the air passing through the second space is slower than an air speed of the air passing through the first space.

  • Patent number: 5995784
    Abstract: A safety mechanism for an open/close door member of an image forming apparatus includes a door member rotated around one axis to be opened and closed in a gravity force direction, a first lever member abutting against the door member in a closed condition, a second lever rotatably attached to an apparatus body and adapted to support the first lever member, and a biasing member for biasing the first and second lever members. When a load acting on the first lever member from the door member is greater than a set value, the lever member is shifted to a predetermined position to function as a stop device for stopping rotation of the door member, and, when the load is smaller than the set value, the rotation of the door member is permitted.
