摘要： An insertion passage 104Y for inserting a suction nozzle 73Y fixed to an image forming apparatus is provided on a holder 102Y, and a connecting passage 114Y that connects the insertion passage 104Y and a toner storage section 106Y of the holder 102Y is provided. After the toner sent from bottle 101Y to the holder 102Y falls towards the connecting passage 104Y, the toner flows into the suction nozzle 73Y through the connecting passage 114Y and is then discharged out of the holder 102Y. An airtightness between the insertion passage 114Y and the suction nozzle 73Y inserted into the insertion passage 114 Y is superior than an airtightness between the bottle 101Y and the holder 102Y engaged with the bottle 101Y.

摘要： In a toner collecting device of the present invention for conveying collected waste toner to a waste toner storing portion with a toner conveying device, the toner conveying device is positioned at a side opposite to a driveline included in an apparatus body to which the toner collecting device is mounted. A driveline for driving the toner conveying device is not arranged at the side opposite to the driveline of the apparatus body, but the toner conveying device is directly driven by the driveline of the apparatus body. With this configuration, the toner collecting device is capable of driving, e.g., a toner conveying belt or a toner conveying screw arranged at the counter drive side without sophisticating the configuration.

摘要： A developing device, used in an image forming device where a developer supported on a developer supporter is thinned by a thinning member, and after being thinned, the developer is adhered to develop a latent image on an image supporter. An adjacent member (a developer scattering blocking member) is disposed at a position adjacent to the thinning member's downstream side in the developer supporter's moving direction, and the adjacent member's thinning member side of the opposite surface that is opposite to the developer supporter and the tip of the thinning member are disposed with an equal distance from the developer supporter. The opposite surface is gradually separated from the developer supporter at the downstream side of the developer supporter's moving direction.

摘要： An image forming apparatus is provided, which includes an image bearing member, a transfer roller having a shaft for transferring an image on the image bearing member to a transfer sheet, a bearing mechanism for supporting the shaft, a discharging device for discharging the transfer, and a joint mechanism which mechanically connects the discharging device with the transfer roller at both ends of the shaft. Both of the transfer roller and the discharging device can be integrally detached from and attached to the image forming apparatus without detaching/attaching the bearing mechanism, by use of a handle. Therefore, an operation for replacing the transfer roller and the discharging device can be performed easily.

摘要： A toner bottle has a bottle body (1) containing toner and a cap (5) closing an opening portion (3) formed in the bottle body (1), and toner is supplied through the opening portion (3). A plateshaped toner scraping member (20) extending into the opening portion (3) and having elasticity is provided on the back surface of the cap (5) in the diameter direction of the cap (5). Also, the outer end of the toner scraping member (20) is positioned inside of the bottle body (1) beyond the opening portion (3) even when the cap (5) is in its cap-opened position. If the toner bottle is constructed in this way, the toner on the opening portion (3) will be scraped by the toner scraping member (20) and toner condensation can be reliably prevented at the opening portion (3) when toner is supplied from the bottle body (1) by rotation of the toner bottle.
