Image forming apparatus

An image forming apparatus comprising:

• an image forming portion which forms an image on a sheet;
• a cassette which stores a sheet;
• a pickup roller which picks up the sheet inside the cassette;
• a feed roller which feeds the sheet picked up by the pickup roller toward the image forming portion and is attached to one end of a shaft;
• a separation member which is provided in a position facing the feed roller, forms a separation nip by being pressed against the feed roller, and separates a plurality of sheets picked up by the pickup roller one by one at the separation nip;
• a rail which supports the cassette and along which the cassette is drawn in a drawing direction orthogonal to a conveying direction;
• and
• a conveying guide which guides the sheet picked up by the pickup roller to the separation nip,
• the conveying guide including:
• a first guide member which is located above the separation nip in a vertical direction and is located further downstream of the cassette in a drawing direction than the feed roller;
• a second guide member which is located above the separation nip in the vertical direction and is located further upstream of the cassette in the drawing direction than the feed roller;
• and
• a third guide member which is located below the separation nip in the vertical direction and is located in a position where the third guide member overlaps with the feed roller in the drawing direction,
• the first guide member
• being configured to be slidable in the drawing direction when the feed roller is detached from the shaft and
• being formed of a material whose property of light transmittance of light having a wavelength of 360 nm to 420 nm is 80% or more,
• each of the second and third guide members
• being formed of a material whose light transmittance of the light having the wavelength of 360 nm to 420 nm is less than 80%,
• the feed roller
• being detachable from the one end of the shaft in a state in which the cassette is drawn out along the rail and the first guide member is slid in the drawing direction.
