Abstract: A toner collection device includes a casing, a fan unit and a filter. The casing has a suction port and an exhaust port. The fan unit is supported by the casing in a swingable manner and generates an air flow from the suction port to the exhaust port inside the casing. The filter is disposed inside the casing and supported by the casing or the fan unit, and collects a toner contained in the air flow flowed into the casing through the suction port. When the fan unit is driven to generate the air flow, a swinging of the fan unit is transmitted to the filter to vibrate the filter.

Abstract: An image forming apparatus includes a toner conveyance device and a controller. The toner conveyance device includes a casing, a screw and a film. The casing has a toner conveyance path. The screw rotates in a first rotational direction to convey a toner stored in the toner conveyance path in a predetermined conveyance direction. The film is attached to the screw and rotating together with the screw while coming into contact with an inner face of the toner conveyance path to be elastically deformed. The controller executes a toner conveyance control to rotate the screw and the film in a first rotational direction and a reverse rotation control to rotate the screw and the film in a second rotational direction opposite to the first rotational direction.

Abstract: An image forming apparatus of the present disclosure includes a developing device and a toner storage container. The toner storage container is detachable and attachable with respect to an apparatus main body. The toner storage container includes a supply screw which conveys toner by rotating forward, and a first engagement unit coupled via a gear train to a rotation shaft of the supply screw. The apparatus main body includes a second engagement unit which engages with the first engagement unit to restrain detachment/attachment of the toner storage container by engaging with the first engagement unit. In a case where an amount of toner in the toner storage unit has become equal to or less than a predetermined amount, a control unit makes the supply screw rotate backward to thereby release engagement between the first and second engagement units.

Abstract: A toner collecting unit includes a housing, an inlet, a first fan, a lower duct, a first filter, and an oscillation motor. The inlet is provided in the housing. Toner flows into the inlet together with an air flow. The first fan is arranged in the interior of the housing and is configured to suck the air flow flowing from the inlet and to exhaust the air outside the housing. The lower duct guides the air flow upward from below. The first filter is arranged in an upper part of the lower duct so that its approach surface, which the air flow enters, faces downward.

Abstract: A developer supplying device has a storage container, a detection sensor, and a cleaning member. The storage container stores developer. The detection sensor has a detection face making contact with the developer in the storage container and detects the amount of developer in the storage container. The cleaning member cleans the detection face by making contact with the detection face. The storage container has a sensor movement face formed arc-shaped about a predetermined center as seen in a sectional view. The detection sensor is configured to be movable in the up/down direction along the sensor movement face. The cleaning member rotates about the predetermined center as a rotation axis.

Abstract: A toner conveying device includes a common conveyance path, toner input paths and blades. A screw for conveying a toner is installed in the common conveyance path. The toner input paths extend in an up-down direction and have lower ends connected to the common conveyance path. The blades are installed so as to make contact with a shaft of the screw and are configured to scrape off a toner adhering to the shaft of the screw. The blades are arranged immediately below the toner input paths so as to make contact with the shaft of the screw. The blades are disposed at a pitch of an integer multiple of a pitch of the fin of the screw.
