Image reading apparatus and image forming system

An image reading apparatus comprising:

• a reader which reads an image on a sheet at a predetermined reading position;
• a conveying path which guides the sheet having the image to the reading position and which guides the sheet read by the reader in an ejecting direction;
• a conveyer which conveys the sheet along the conveying path;
• a conveyer driving unit which drives the conveyer;
• a conveyer housing which supports the conveying path, the conveyer, and the conveyer driving unit;
• a lighting unit which is fixed to an interior of the reader and which illuminates the sheet conveyed by the conveyer to the reading position;
• a cooler which cools the lighting unit;
• and
• a frame which separately fixes the reader and the conveyer housing,
• wherein the cooler is fixed to the conveyer housing, and
• wherein the cooler, the frame, the conveyor housing, and the reader are configured so that vibrations generated by the cooler are attenuated through the conveyor housing and the frame before reaching the reader.
