Abstract: An image forming apparatus includes an image carrier unit, a developing unit, a supporting frame, a retainer and a sheet member. The image carrier unit includes an image carrier on which an electrostatic latent image is formed. The developing unit develops the electrostatic latent image with toner. The supporting frame supports the image carrier unit and the developing unit in an attachable and detachable manner. The retainer is supported by the supporting frame in a turnable manner, and positions the image carrier unit and the developing unit to the supporting frame by being turned upward. The sheet member closes a gap between the supporting frame and the retainer. The sheet member has an upper section supported by the retainer and a lower end section supported by the supporting frame, and at least one of the upper end section and the lower end section is configured to be detachable.

Abstract: An image forming apparatus according to an aspect of the present disclosure includes a toner conveyance portion, a vent hole portion, an air suction portion, and a filter portion. The toner conveyance portion forms a toner conveyance passage between a developing device and a collection container such that toner discharged from the developing device is conveyed in the toner conveyance passage and collected in the collection container. The vent hole portion is formed in the toner conveyance portion and allows inside and outside of the toner conveyance portion to communicate with each other such that air can be ventilated between the inside and the outside of the toner conveyance portion. The air suction portion sucks the air inside the toner conveyance portion via the vent hole portion. The filter portion is disposed on the vent hole portion and traps toner contained in the air sucked by the air suction portion.

Abstract: The image forming apparatus includes an image carrier unit, a developing device, a unit support frame, and a developing holder. The developing holder is provided on the unit support frame, and holds the developing device such that the developing device is swingable in a direction that allows the developer carrier to get nearer to or further separate from the image carrier. The developing holder includes a driving gear and a pair of swinging shaft parts. The driving gear transmits motive power to the developing device. The pair of swinging shaft parts have a rotational axis extending parallel to an axial direction of the developer carrier and are supported rotatable relative to the unit support frame. An axial distance between the pair of swinging shaft parts is longer than a distance from a rotational center of the driving gear to a rotational center of the swinging shaft parts.
