Image forming apparatus

An image forming apparatus for forming an image on a recording medium, the image forming apparatus comprising:

• an apparatus main body including (i) a housing having a discharge portion and (ii) a door being openable and closable relative to the housing, the door including a wall disposed on an opposite side to the discharge portion with respect to a horizontal direction, wherein the discharge portion includes a first opening for discharging the recording medium, and the wall includes a second opening, the second opening including a plurality of holes;
• a photosensitive drum stored in the apparatus main body, wherein the photosensitive drum is rotatable and disposed below the first opening and the second opening with respect to a vertical direction, and when viewed in a rotational axis direction of the photosensitive drum, the photosensitive drum is disposed between the first opening and the second opening in the horizontal direction;
• a transfer member contacting the photosensitive drum such that a transfer portion, through which the recording medium passes, is formed between the photosensitive drum and the transfer member, wherein a toner image formed on the photosensitive drum is transferred onto the recording medium at the transfer portion;
• a fixing unit configured to heat the recording medium, the fixing unit disposed above the photosensitive drum;
• an opposed member facing a two-sided conveying path including a first communication path, the first communication path communicating with the first opening and the second opening, the opposed member including:
• (i) an exposed surface stored in the apparatus main body, wherein the exposed surface is exposed toward the first communication path and disposed below the first communication path,
• (ii) a plurality of ribs arranged along the rotational axis direction of the photosensitive drum, wherein the plurality of ribs projects from the exposed surface toward the first communication path, and each of the plurality of ribs extends in a direction intersecting with the rotational axis direction,
• (iii) a receiving rib projecting from the exposed surface and including a receiving surface projecting from the exposed surface toward the first communication path;
• and
• an opening/closing member disposed below the opposed member and supporting the transfer member, and the opening/closing member being movable between (i) a closed position in which the opening/closing member covers the photosensitive drum and the transfer member is in contact with the photosensitive drum and (ii) an open position in which the photosensitive drum is exposed and the transfer member is separated from the photosensitive drum,
• wherein, in a state where the opening/closing member is at the closed position, a second communication path is formed between the opening/closing member and the opposed member, the second communication path is formed above the photosensitive drum and below the first communication path with respect to the vertical direction, and the second communication path communicates with a conveyance path through which the recording medium is conveyed from the photosensitive drum toward the fixing unit, and communicates with the two-sided conveying path,
• wherein the receiving surface is upwardly oriented with respect to the vertical direction and faces the first communication path, and the receiving surface extends along the rotational axis direction to connect with the plurality of ribs and is disposed to be positioned above the photosensitive drum with respect to the vertical direction,
• wherein the receiving surface is inclined relative to the vertical direction and the horizontal direction so that a leading end of the receiving surface is disposed above a root of the receiving surface connecting with the exposed surface, and
• wherein the receiving surface is positioned above the second communication path and
• when viewed in the rotational axis direction of the photosensitive drum, the receiving surface is closer to the second opening than to the first opening.
