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: In an image forming apparatus, a dust collecting unit is disposed in the front side of image forming units. The dust collecting unit includes a dust collecting box and a fan. The dust collecting box is communicated with developer cases. The fan sucks air in the dust collecting box and discharges the air. The fan sucks air that has passed through a filter in the dust collecting box and discharges the air to an exhaust duct. The exhaust duct is disposed between a toner container and a fixing device and forms an air passage that extends in a front-rear direction to reach an opening portion provided in the rear side. The air is discharged to an outside of the apparatus from the opening portion.

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 includes: an apparatus body; a body cover: photoreceptor drums; developing devices; toner containers; container covers; lock release mechanisms; pressing units; latching parts; and interlocking mechanisms. Each of the plurality of pressing units presses the toner container toward the container cover within the apparatus body. Each of the plurality of latching parts latches the toner container against pressing force of the pressing unit at a replenishment position where the toner is replenishable to the developing device within the apparatus body. Each of the plurality of interlocking mechanisms moves the toner container from the replenishment position to a side of the container cover by the pressing force of the pressing unit by releasing the latch of the latching part to the toner container in conjunction with lock release of the container cover by the lock release mechanism.

Abstract: An image forming apparatus includes a storage container, a detection portion, a determination portion, a first calculation portion, and a first notification processing portion. The storage container stores waste toner collected. The detection portion detects that an amount of waste toner stored in the storage container has reached a predetermined reference amount. The determination portion determines, after the detection portion detects that the amount of waste toner has reached the predetermined reference amount, whether the storage container is in a full state. The first calculation portion calculates a set time based on a waste toner increase speed at which the waste toner increases up to a point of time of the detection by the detection portion. The first notification processing portion, when the set time has elapsed since the point of time of the detection by the detection portion, makes a notification regarding a pre-full state.

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.
