Patent ID: 8290414

Claim:
An image forming apparatus comprising: an image bearing member; a toner image forming portion for forming a toner image on said image bearing member; a rotatable transfer member, pressing a recording material toward said image bearing member, for forming a transfer portion for transferring the toner image from said image bearing member onto a recording material; and a pair of regulating portions, provided at a position downstream of the transfer portion with respect to a normal conveyance direction of the recording material, for suppressing movement of the recording material toward said image bearing member, wherein at least a part of each of said regulating portions is provided on a rectilinear line perpendicular to the conveyance direction; wherein each regulating portion contacts a lateral side of the recording material, respectively, passing through the transfer portion, and the recording material is bent and deformed in a shape of an arc so that a stiffness of the recording material is enhanced, and each regulating portion includes an end portion at an image bearing member side and a base portion at a transfer member side, so that a width between the regulating portions is decreased from the base portion toward the end portion, and wherein a width between the base portions is narrower than a width of the recording material passing through the transfer portion, with respect to a width direction.
