A fixing apparatus for use in an electrophotographic copying machine for fixing a toner image on the surface of a recording paper. The fixing apparatus is provided with a fixing means to fix the toner image on a recording paper, ejecting means to eject the recording paper after the fixation of the toner image and a correcting roller located along the ejecting path of the recording paper to correct a curl of the recording paper induced during the fixing process by bending the recording paper in an opposite curvature of the curl.

Fixing apparatus

Toner cartridge for copier

A toner seal method and apparatus, wherein the leakage of a residual toner on a photosensitive member surface, which is removed by a blade of a photosensitive member cleaning device inside an electrophotographic recording apparatus and stored in a recovery casing is prevented by a toner seal member. The seal member is folded so as to come into contact with the photosensitive member surface, an end surface of the blade and an end surface of a toner guide plate for the casing and bonded to the casing near a photosensitive member.

Toner seal method and apparatus in electrophotographic recording

An electrostatic recording apparatus having a cleaning device and/or a developing device, in which a container is provided and a seal member is mounted on the container. The seal member is inserted in a groove formed in the circumferential surface of an end portion of a photosensitive drum.

Electrostatic recording apparatus

An image recording apparatus having a toner reservoir. The toner reservoir is removably mounted on the process cartridge or a developing device in the image recording apparatus. The toner reservoir is composed of a supply toner reserving unit having a supply opening and a recovery toner container having a waste toner recovery opening. The supply toner reserving unit and said recovery toner reserving unit are connected with each other through a connecting member, the supply toner reserving unit being arranged rotatably while the recovery toner reserving unit being fixed with the recovery opening thereof facing upward.

Image recording apparatus having toner reservoir

A toner cartridge for supplying a toner to a photo-copy machine and collecting a waste portion of the toner after a copy operation with the photo-copy machine, comprising; a cylindrical body for providing a supplement toner containing room and a waste toner collecting room by means of a separating wall inside, the separating wall for dividing the supplement toner containing room and the waste toner collecting room, an outlet being located on the wall of the cylindrical body at the side of the supplement toner containing room for supplying the toner contained in the room into the photo-copy machine, and an inlet being located on the wall of the cylindrical body at the side of the waste toner collecting room for collecting the waste portion of the toner from the photo-copy machine, in which the separating wall is angled so that its surface is leaned toward the supplement toner containing room or the waste toner collecting room.

Toner cartridge for a copying apparatus

The invention provides a toner recovery device for collecting toner from a cleaning device into a recovery toner container. The device includes a toner conveyance, an operating lever and a shutter. The tone conveyance has a conveyance pipe whose base end portion is rotatably connected to the cleaning device and tip end portion with an outlet opening is detachably coupled to an inlet opening of the recovery toner container so that the tip end portion is pivotted around the base end portion so as to take the coupled position and the detached position. The operating lever is linked to the conveying pipe for pivotting the tip end portion between the coupled position and the detached position. The shutter is adapted to move on the conveying pipe interlockingly with the movement of the operating lever so that the shutter closes the outlet opening of the conveying pipe on the detached position and opens the outlet opening on the coupled position.
