Image forming apparatus

An image forming apparatus, comprising:

• an image forming unit configured to form an image on a sheet;
• a first re-conveyance guide configured to guide a sheet on which an image is fored in a re-conveying direction;
• a second re-conveyance guide disposed downstream of the first re-conveyance guide in the re-conveying direction and configured to guide the sheet along a path extending from the first re-conveyance guide to the image forming unit;
• a side guide provided at one end portion of the second re-conveyance guide in a widthwise direction orthogonal to the re-conveying direction and configured to contact one end portion of the sheet to regulate the sheet;
• a side chute provided at one end portion of the first re-conveyance guide in the widthwise direction and configured to guide the sheet in the re-conveyance direction toward the side guide;
• and
• a positioner formed integral with the second re-conveyance guide, the positioner being engaged with an upstream end portion of the side guide in the re-conveying direction to position the side guide with respect to the second re-conveyance guide, the positioner being engaged with a downstream end portion of the side chute in the re-conveying direction to position the side chute with respect to the second re-conveyance guide,
• wherein the positioner comprises a first contact portion configured to contact a first engaged portion from a downstream side in the re-conveying direction, the first engaged portion extending downward from the upstream end portion of the side guide, and a second contact portion configured to contact the first engaged portion from an upstream side in the re-conveying direction.

An image forming apparatus comprising:

• an image forming unit configured to form an image on a sheet;
• a first re-conveyance guide configured to guide a sheet on which an image is formed in a re-conveying direction;
• a second re-conveyance guide disposed downstream of the first re-conveyance guide in the re-conveying direction and configured to guide the sheet along a path extending from the first re-conveyance guide to the image forming unit;
• a guide wall provided at one end portion of the second re-conveyance guide in a widthwise direction orthogonal to the re-conveying direction and configured to contact one end portion of the sheet to regulate of the sheet;
• a side chute provided at one end portion of the first re-conveyance guide in the widthwise direction and configured to guide the sheet in the re-conveyance direction toward the guide wall;
• and
• an engaging portion provided on the second re-conveyance guide,
• wherein the engaging portion is engaged with a first engaged portion extending downward from an upstream end portion of the guide wall in the re-conveying direction and is engaged with a second engaged portion provided on a downstream end portion of the side chute in the re-conveying direction, and
• wherein the engaging portion comprises a first surface configured to contact the first engaged portion from a downstream side in the re-conveying direction, and a second surface configured to contact the first engaged portion from an upstream side in the re-conveying direction.
