Image forming apparatus having a cover to cover image forming units

An image forming apparatus comprising:

• a first image forming unit of a plurality of image forming units, wherein the first image forming unit includes a first photosensitive member, a first charging unit configured to charge the first photosensitive member, a first exposure unit configured to expose the first photosensitive member charged by the first charging unit to form an electrostatic latent image on the first photosensitive member, and a first development unit configured to develop the electrostatic latent image formed on the first photosensitive member with toner;
• a second image forming unit of the plurality of image forming units, wherein the second image forming unit includes a second photosensitive member, a second charging unit configured to charge the second photosensitive member, a second exposure unit configured to expose the second photosensitive member charged by the second charging unit to form an electrostatic latent image on the second photosensitive member, and a second development unit configured to develop the electrostatic latent image formed on the second photosensitive member with toner;
• a first cover configured to be opened and closed and forming part of an exterior of the image forming apparatus;
• a second cover located between the first cover and the plurality of image forming units in a rotational axis direction of the first photosensitive member, wherein the second cover is made of resin and covers the plurality of image forming units;
• an air intake including a first air intake and a second air intake;
• a first duct disposed on the second cover and configured to guide air sucked from outside of the image forming apparatus through the first air intake to the first image forming unit;
• a second duct disposed on the second cover and configured to guide air sucked from the outside of the image forming apparatus through the second air intake to the second image forming unit;
• a third cover configured to be attached, in an attachable and detachable manner, to the second cover to cover an opening of the second cover, wherein at least part of the first image forming unit is insertable and extractable through the opening of the second cover;
• a first fan configured to suck air into the first duct through the first air intake, wherein the first fan is arranged outside of the plurality of image forming units in an arrangement direction of the plurality of image forming units;
• and
• a second fan configured to suck air to be fed to the second duct through the second air intake, wherein the second fan is arranged on a side of the plurality of image forming units that is opposite in the arrangement direction of the plurality of image forming units from a side of the plurality of image forming units on which the first fan is arranged.
