Abstract: In a waste toner collecting device, primary cleaning devices and a secondary cleaning device remove residual toner that has remained on photoconductor drums and an intermediate transfer belt, respectively. A conveyance path guides the residual toner in a downstream direction. A toner container stores, as waste toner, the residual toner discharged from a downstream end of the conveyance path. A toner amount sensor outputs a detection signal whose level changes in correspondence with an amount of the waste toner. A derivation portion derives an accumulated value of the residual toner based on image data each time an image formation is performed. A determination portion determines whether or not an abnormality has occurred in the waste toner collecting device based on the level of the detection signal and the accumulated value.

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.

Abstract: A toner case includes a case main body, a housing frame, a communicating port, a conveying rib, and a conveying screw. The case main body is capable of containing a waste toner. The housing frame is configured to communicate with an inside of the case main body and to rotatably support the case main body. The communicating port is opened on a circumferential face of the housing frame and connected with an image forming part. The conveying rib rotates integrally with the case main body in a first direction so as to convey the waste toner along a direction of introducing the waste toner into the case main body. The conveying screw rotates integrally with the case main body in the first direction so as to convey the waste toner introduced into the housing frame via the communicating port toward the inside of the case main body.
