Patent number: 9823601Abstract: According to an embodiment, a developer-supplying container includes a container and a paddle. The container includes an opening for supplying the image forming apparatus with developer contained in the container. The paddle conveys the developer to the opening by rotating within the container. The paddle includes a first arm. The first arm has a shape that is wider on an upstream side in a direction of the rotation of the paddle and narrower toward a downstream side. In addition, the first arm is disposed such that a narrowest portion of the first arm is located at the same position as the opening in a direction of a shaft.Type: GrantFiled: July 28, 2016Date of Patent: November 21, 2017Assignees: KABUSHIKI KAISHA TOSHIBA, TOSHIBA TEC KABUSHIKI KAISHAInventors: Noriyuki Yokoyama, Eiji Gumbe

Patent number: 7333751Abstract: According to the present invention, when inserting and removing EPUs from an image forming unit, a support leg of a casing can swing, is inclined, and avoids easily a structural body on a path. Further, when putting the EPUs outside the main body of the image forming apparatus, the support leg is fixed to the casing. Therefore, the space for the support leg of the casing of the image forming unit to insert through can be reduced.Type: GrantFiled: August 19, 2005Date of Patent: February 19, 2008Assignees: Kabushiki Kaisha Toshiba, Toshiba TEC Kabushiki KaishaInventor: Eiji Gumbe

Patent number: 7127197Abstract: An image forming apparatus includes a main body, an image carrier provided in the main body and configured to retain electrostatic latent images on its surface, and a developing unit including a holding unit holding plural developing devices, rotatably supported by the main body. Further, a driving source is configured to rotate the developing unit and move a desired developing device to a developing position opposed to the image carrier. A stopping member is configured to be moved to an unstopping position unengaged with the holding unit and to a stopping position to stop a one-way direction rotation of the developing unit at an exchanging position for exchanging the developing devices. A backstop member is configured to be moved to a removing position unengaged with the holding unit and to an engaged position engaged with the holding unit to prevent a rotation of the developing unit in a direction opposite the one-way direction rotation.Type: GrantFiled: September 19, 2005Date of Patent: October 24, 2006Assignees: Kabushiki Kaisha Toshiba, Toshiba Tec Kabushiki KaishaInventor: Eiji Gumbe
