  • Patent number: 9740142
    Abstract: A toner case includes a case main body and a cleaning member. The case main body is capable of containing a toner supplied to an image forming part arranged inside an apparatus main body and is attachable to and detachable from a supplying attachment part of the apparatus main body along an attachment and detachment direction. The cleaning member is arranged at an outer circumferential face of the case main body. The case main body rotates inside the supplying attachment part in a first direction so as to convey the toner toward a communicating port formed at a first side in the attachment and detachment direction. The cleaning member rotates integrally with the case main body in the first direction so as to clean an inner circumferential face of the supplying attachment part.

  • Publication number: 20170219986
    Abstract: An image forming apparatus includes a toner container, a container attachment portion, and a control portion. The toner container has a coupling portion. The container attachment portion includes a coupled portion that includes a first key member. A second key member of the coupling portion is formed at position where it does not interfere with the first key member in attachment state. The second key member is made of insulator. The coupled portion includes a contact terminal in which a contact is opened by the second key member and becomes OFF state when the toner container is inserted to attachment position, and the contact is closed and becomes ON state when the toner container is removed from the attachment position. The control portion detects the toner container attached to the container attachment portion when the contact of the contact terminal changes from the ON state to the OFF state.

  • Patent number: 9285710
    Abstract: In an initial recovery stage of untransferred toner, a conveying stirring screw is rotated at a high speed by using a second driving path. When the amount of collected untransferred toner increases and the rotating torque of the conveying stirring screw reaches a setting torque value of a second torque limiter, a driving path is switched to a first driving path, so that the conveying stirring screw is rotated at a low speed. When the amount of the collected untransferred toner further increases and the rotating torque of the conveying stirring screw reaches a setting torque value of a first torque limiter, the first driving path is also disconnected to block torque transfer to the conveying stirring screw.
