Image forming apparatus

An image forming apparatus comprising:

• a main conveying path along which a sheet is conveyed upward to an image forming part;
• a conveying roller pair provided on the main conveying path, the conveying roller pair configured to deflect the sheet by stopping its rotation such that a front edge of the sheet abuts against the conveying roller pair to correct a skew of the sheet and then to convey the sheet to the image forming part by stating its rotation at a predetermined timing;
• a joining section provided on an upstream side from the conveying roller pair in a sheet conveying direction;
• an upper sheet feeding part configured to feed the sheet;
• a lower sheet feeding part provided under the upper sheet feeding part and configured to feed the sheet;
• an upper conveying path along which the sheet fed from the upper sheet feeding part is conveyed and configured to join the main conveying path at the joining section;
• a lower conveying path along which the sheet fed from the lower sheet feeding part is conveyed and configured to join the main conveying path at the joining section;
• a conveying guide provided in the joining section and configured to guide the sheet to the conveying roller pair along the main conveying path;
• and
• a sheet member provided in the joining section, the sheet member being configured to form the lower conveying path with the conveying guide and to guide the sheet from the upper conveying path toward the main conveying path:
• wherein the conveying guide includes
• a convex guide part provided at a center portion in a sheet width direction orthogonal to the conveying direction and projecting toward the sheet member, and
• planar guide parts provided on both sides in the width direction of the convex guide part, and
• wherein a first gap formed between the convex guide part and the sheet member is narrower than a second gap formed between each of the planar guide parts and the sheet member.
