  • Patent number: 11067938
    Abstract: Provided are a cleaning member that removes a developer from the surface of an image bearing member that is attached to an opening of a frame; a transport member that transports developer removed from the surface of the photosensitive member drum by the cleaning member, from an opening side of the frame towards an opposing deep side; and a driving unit for driving the transport member such that the transport member moves relatively to the cleaning member. The transport member is driven by the driving unit such that an absolute value of maximum acceleration at the time of movement of the transport member in a direction from the opening side of the frame towards the deep side is smaller than an absolute value of maximum acceleration at the time of movement in a direction from the deep side towards the opening side.

  • Patent number: 10928768
    Abstract: Provided are a cleaning member that scrapes developer from a photosensitive drum attached to an opening of a cleaning frame, and a transport member that transports scraped developer from an opening side of the frame towards an opposing deep side. The transport member is driven such that an absolute value of maximum acceleration at the time of movement of the transport sheet in a direction from the opening side towards the deep side is smaller than an absolute value of maximum acceleration at the time of movement in a reverse direction of the former direction. In the longitudinal direction of the photosensitive drum, the width of the transport member is smaller than an abutting width of an abutting portion of the cleaning member with the photosensitive drum, and ends of the transport member in the longitudinal direction are positioned inward of ends of the abutting portion.

  • Publication number: 20200310298
    Abstract: A cartridge includes a housing that has an opening and a conveyance member disposed near a bottom surface of the housing. The conveyance member is configured to convey developer along a first direction from a deep side to an opening side of the housing, or a second direction from the opening side to the deep side. The cartridge also includes a driving member connected to one end of the conveyance member, with the driving member being configured to reciprocate the conveyance member along a surface direction of the conveyance member in a manner such that a maximum acceleration of the conveyance member in the first direction and a maximum acceleration in the second direction are different from each other. The housing includes a regulation member that regulates movement of the conveyance member in a direction in which the conveyance member moves away from the bottom surface of the housing.

  • Publication number: 20200310294
    Abstract: A developing device includes a rotatable developer carrying member, a frame, a partition wall partitioning an inside of the frame into a developing chamber and a developer accommodating portion and provided with an opening, and a feeding member. The feeding member includes a flexible sheet member and a driving member. Maximum acceleration of the sheet member driven by the driving member in a first direction in which the developer in the developer accommodating chamber is moved toward the opening is smaller than maximum acceleration in a second direction opposite to the first direction. When the sheet member is reciprocated in a surface direction by the driving member, the sheet member is deformable so as to follow a shape of an inner wall surface of the developer accommodating chamber.

  • Patent number: 9244190
    Abstract: Technologies are generally described for transmitting electric power using electromagnetic waves. An example device may include a transmitting unit, a dielectric waveguide, and a receiving unit. The transmitting unit can be configured to transmit the electromagnetic wave through a first waveguide. The dielectric waveguide can be configured to direct the electromagnetic wave from the first waveguide to a second waveguide. Further, the receiving unit can be configured to receive the electromagnetic wave from the dielectric waveguide through the second waveguide. An example borehole radar system may generate an electromagnetic wave from a DC power supply and provide the electromagnetic wave to a power transmitting unit. The power transmitting unit can be configured to transmit the electromagnetic wave through a dielectric waveguide. The electromagnetic wave can be rectified to generate a DC voltage signal, by which a transmitting antenna may be powered to generate a radar signal.
