Patent ID: 8666284

Claim:
An image forming apparatus comprising: an image bearing member configured to bear a toner image; a movable belt member configured to convey a recording material; a transfer member configured to electrostatically transfer the toner image formed on the image bearing member to the recording material conveyed by the belt member; a push-up member configured to push up, from an inner side of the belt member, the belt member at a position downstream of the transfer member in a recording-material conveying direction for forming a plurality of local projecting portions at the belt member in a width direction of the belt member; a separation belt-stretching member around which the belt member is stretched, the separation belt-stretching member being disposed downstream of the push-up member in the recording-material conveying direction and configured to separate the recording material; and a recording material guide having a guide surface and disposed downstream of the separation belt-stretching member in the recording-material conveying direction, the recording material guide being configured to guide the recording material separated from the belt member with the guide surface; wherein, when a space is divided into two regions by a tangent plane of a surface of the separation belt-stretching member and passing through a point where the belt member starts to come into contact with the separation belt-stretching member on a plane perpendicular to a width direction of the belt member and passing through a lowest point of a concave portion at the belt member between the local projecting portions formed by the push-up member, an upstream end of the guide surface of the recording material guide, in the recording-material conveying direction, is located in a region, where the separation belt-stretching member is located, of the two regions.
