Image reading apparatus and image forming apparatus

An image forming apparatus comprising:

• a transparent member on which a sheet is placed;
• a reading unit that includes light receiving elements arrayed in a main scanning direction, and that is configured to read an image on the sheet placed on the transparent member;
• a shaft member extending in a sub-scanning direction;
• a holding member that includes a first hole, and that is configured to hold the reading unit so that the reading unit is movable along the shaft member;
• a sliding member that includes a second hole, that is attached to the holding member, and that is configured to slidably move with respect to the shaft member;
• a screw that is configured to fix the sliding member to the holding member;
• a plate that includes a screw hole to which the screw is threadedly fitted;
• and
• an image forming unit configured to form an image on a recording medium based on the image read by the reading unit,
• wherein the screw inserted into the first hole and the second hole is threadedly fitted to the screw hole in a state where the holding member is sandwiched by the plate and the sliding member, whereby the sliding member is fixed to the holding member.
