A developer collecting container, mountable to and dismountable from an accommodating portionprovided in an apparatus, for collecting a collected matter which is powder or a fluid collected in the apparatus has a constitution in which a bonding portionpartially bonding opposing sides of sides forming an accommodating portionfor accommodating the collected matter is provided and in which at least a part of the bonding portionis positioned below a height at which a volume of the accommodating portionis half of a target collecting volume in a case that the volume is measured upwardly from a lowermost portion with respect to a direction of gravitation.

Developer collecting container

A cleaning device includes a cleaning member, a container, a feeding screw including a blade for feeding toner inside the container toward an outside of the container, and a loosening member, stretching along a rotation axis direction of the feeding screw, for loosening toner on a container wall surface provided around the feeding screw by being swung about a rotational axis along the rotation axis direction in a direction crossing the rotation axis direction, and the loosening member includes a contact portion for rotating the loosening member in a first direction with rotation of the feeding screw in contact with the blade when the feeding screw is in a predetermined phase range and includes an urging portion for imparting, to the loosening member, a force for rotating the loosening member in a second direction opposite to the first direction.

Cleaning device and image forming apparatus

An image forming apparatus includes an image developer unit to develop an electrostatic latent image formed on an image bearing member, using toner, and a toner container detachably mounted to a main assembly. The toner container includes a toner discharging portion having a toner discharge opening, and a storage container to store the discharge toner and to supply the stored toner. The toner discharging portion extends at least partly in the storage container through an opening of the storage container, and a cover covers the toner discharging portion and extends inwardly from an inside of a wall of the storage container, at least below the toner discharging portion. A length Lby which the cover extends from the wall inwardly of the storage container, and a length Lby which the toner discharging portion extends from the opening inwardly of the storage container satisfy L&#x3c;L

Image forming apparatus having a toner discharging portion and a cover

An image forming apparatus includes an image forming unit having a rotatable image bearing member, a first support side plate, and a second support side plate; a development device; a transfer device; a rotatable stay; an operation portion; and a toner containing portion. The rotatable stay is disposed at a position downstream of the development device and upstream of the transfer device with respect to a rotation direction of the image bearing member to face the image bearing member and to connect the first support side plate and the second support side plate. The operation portion is provided at an end portion of the stay to rotate the stay. The toner containing portion contains the toner accumulated on the stay.
