    摘要: A first rotary image carrier is adapted to support a toner image obtained by developing an electrostatic latent image formed thereon. A second rotary image carrier is adapted to support, on a toner supporting face thereof, the toner image which has been primarily transferred from the first rotary image carrier and is to be secondarily transferred onto a recording medium. A cleaner housing has wall members defining a housing space, a first one of which is formed with a first ventilation hole. A blade member is disposed in the housing space and configured to separatably come in contact with the second rotary image carrier to scrape off toner remaining thereon. A sealing member is disposed in the housing space and configured to separatably come in contact with the second rotary image carrier to form a closed space together with the blade member. An air duct, a part of which is formed by an outer face of at least one of the wall members of the cleaner housing, communicates with the housing space through the first ventilation hole.

    摘要: An image forming apparatus is operable to form an image on a recording medium. An image carrier is adapted such that a toner image is formed thereon by developing an electrostatic latent image. An intermediate transfer member is adapted such that the toner image is primarily transferred thereto. In a transfer device, a roller member is adapted to come in contact with the intermediate transfer member. A first bias voltage applier is operable to provide a transfer voltage, thereby applying a first bias voltage between the roller member and the intermediate transfer member to secondarily transfer the toner image onto the recording medium in order to obtain the image. A charge eliminator is disposed in the vicinity of the roller member. A second bias voltage applier is operable to apply a second bias voltage to the charge eliminator to eliminate charges on the recording medium which has been subjected to the application of the first bias voltage. A controller is operable to vary the second bias voltage in accordance a deviation amount of the first bias voltage.

    摘要: A corona charger is provided with a back plate which defines a first space which surrounds a discharge electrode while opening a side that the discharge electrode faces an image carrier. The back plate is formed with a first opening. A storage has a second space which stores waste toner generated in the image forming apparatus. The storage is formed with a second opening. A filter causes ozone to pass through but blocks toner. The filter is disposed between the corona charger and the second space. The first space and the second space are communicated by way of the first opening and the second opening.
