  • Patent number: 8052344
    Abstract: A biodegradable plastic of a screw-fastened portion which remains on a metal component can be decomposed and dissolved by immersing in a degradative enzyme while being joined with the metal component. Further, since the amount of the biodegradable plastic is small and a shape such as a groove is provided which can increase a contact area with the degradative enzyme, decomposition can be completed in a short time.

  • Patent number: 7853166
    Abstract: An image-forming apparatus includes a first unit configured to form an image on a recording medium, a second unit configured to open/close relative to the first unit, and an instructing unit configured to perform an instruction for causing the image-forming apparatus to execute a predetermined operation, wherein the image-forming apparatus is disabled from executing the predetermined operation regardless of whether instruction is performed by the instructing unit when the second unit is in an opened state, and wherein the first unit forms an image on a recording medium regardless of whether the second unit is in an opened state.

  • Patent number: 7742724
    Abstract: A developer supply container supplies developer to a developer receiving portion of a main assembly of an electrophotographic image forming apparatus. The container includes a developer accommodator, a discharge opening, a stirring member, a first receiver receiving a stirring member driving force from a first transmitter in the main assembly, a member opening and closing the opening, a second receiver receiving a force moving the openable member, and a second transmitter transmitting a force to the second receiver through a main assembly relay. By mounting the container to the main assembly, engagements are established between the first transmitter and the first receiver, between the second transmitter and the relay, and between the relay and the second receiver, so that a force is transmittable from the first transmitter to the first receiver, and a is transmittable from the second transmitter to the second receiver.

  • Patent number: 7738817
    Abstract: A developer supply container detachably mountable to a main assembly of an image forming apparatus includes a developer containing portion; a developer discharge opening disposed at the developer containing portion; a container side engaging portion engageable with a main assembly side engaging portion; an operation member; and a transmitting portion in the operation member for transmitting a driving force to a relay portion in the main assembly for opening and closing the developer discharge opening. In a container mounted state, the operation member is capable of opening and closing a main assembly shutter member for opening and closing the developer discharge opening through the relay portion. The container side engaging portion engages with the main assembly side engaging portion when the operation member is moved in a opening direction for opening the main assembly shutter member and releases the engagement when moved in a closing direction for closing the main assembly shutter member.
