The rear end face of the first upright portion of a trailing edge regulating member is brought into contact with the inner face of a notched sidewall provided in a rear sidewall, and the second upright portion is located above the notched sidewall.

Paper feeding cassette and image forming apparatus

The fixing device and image forming apparatus employ a horizontally moving claw for separating a sheet on which a toner image has been fixed. The claw moves in a horizontally reciprocating manner at a velocity between 0.001 mm/seconds to 0.1 mm/seconds. Moving at that speed, it has been found to reduce scratching of the fixing drum. The device and image forming apparatus also employ a claw having a width between 1.0 mm and 5.0 mm. The claw contacts the drum with a pressure in a range of 3.0&#xd7;9.8 mN to 7.0&#xd7;9.8 mN.

Fixing device and image forming apparatus with horizontally moving separating claw

An image apparatus comprising a toner supplying device; a toner receiving device; a first toner conduit communicating with the toner receiving device to feed a toner supplied from the toner supplying device; a first feeding device which forms an air stream to feed the toner through the first toner conduit; and a detector which monitors abnormality condition in the course of toner supplying in the apparatus.

Image forming apparatus which detects abnormality condition in feeding of toner

A toner supplying apparatus for feeding a toner to a developing device to develop a latent image on an image bearing member. The apparatus includes: a toner separating member communicating to the developing device, to separate the toner from the mixed fluid containing the toner and an air stream; a separating side flow control mechanism disposed between the toner separating member and the developing device; a wall to cover at least a portion of the flow control mechanism, having a clearance therebetween; and an after-separation storage to store the toner separated from the mixed fluid.

Toner supplying apparatus and image forming apparatus

A toner conveyance device for conveying toner particles including: a toner mixing unit having a toner introducing portion to introduce toner particles, for mixing the toner particles from the toner introducing portion with air to make a toner fluid; a first conveyor for receiving the toner fluid in the toner mixing unit and conveying; a toner separation unit for separating the toner fluid conveyed by the first conveyor into air and toner particles, the toner separation unit having a toner discharging portion for discharging the separated toner particles to an outside; a second conveyor for conveying the air separated by the toner separation unit back to the toner mixing unit; and a tightly closed circulation path of air, formed starting at the toner mixing unit which leads to the toner separation unit through the first conveyor and returning back to the toner mixing unit through the second conveyor.
