Abstract

A recording material conveying device includes a stripping claw being in contact with one rotary body of a first pair of rotary bodies, and a supporting member supporting a recording material curved when a jam occurs. The supporting member includes a supporting section located more away from the stripping claw than an imaginary straight line (C) passing a nip portion of the first pair of rotary bodies and a surface on a conveying path's side of the stripping claw, and the supporting section supports the recording material curved when the jam occurs. The recording material conveying device further includes a conveyance guide that is disposed on the downstream side from the supporting member and is displaced toward a pressed direction by a pressing force acting when the curved recording material comes into contact with the conveyance guide.

First claim

The invention claimed is:

1. An image forming apparatus comprising:
an image bearing member;
a stripping claw configured to be in contact with a surface of the image bearing member to strip a recording material off the surface of the image bearing member, a toner image having been transferred onto the recording material;
a conveying path for conveying the recording material stripped off by the stripping claw; and
a conveyance guide which is disposed on the stripping claw's side of the conveying path, the conveyance guide including an elastic member which is displaceable by contact with the recording material.

2. The image forming apparatus as claimed in claim 1 , wherein
the conveyance guide includes a platelike elastic member of which edge portion on an upstream side in the conveying path is a fixed edge fixed to a main body and of which edge portion on a downstream side in the conveying path is a free edge.

3. The image forming apparatus as claimed in claim 1 , wherein
the conveyance guide is located in such a manner that the conveyance guide is out of contact with a recording material when a paper jam does not occur.

4. The image forming apparatus as claimed in claim 1 , further comprising:
a first pair of rotary bodies including the image bearing member;
a second pair of rotary bodies which is disposed on a downstream side from the stripping claw in the conveying path; and
a supporting member which is disposed between the stripping claw and the second pair of rotary bodies, the supporting member being located more away from the stripping claw than an imaginary straight line, the imaginary straight line passing a nip portion of the first pair of rotary bodies and a surface on the conveying path's side of the stripping claw, the supporting member supporting the recording material when a paper jam occurs.

5. The image forming apparatus as claimed in claim 4 , wherein
the second pair of rotary bodies includes a pair of fixing rollers for fixing the toner image on the recording material.
