Image forming apparatus having waste toner box

An image forming apparatus comprising:

• a first photoconductor drum configured to rotate about a first axis, and a second photoconductor drum configured to rotate about a second axis, the first axis and the second axis being parallel to each other;
• a belt arranged to face the first photoconductor drum and the second photoconductor drum;
• a main body casing configured to accommodate the first photoconductor drum, the second photoconductor drum and the belt;
• a cover rotatably supported by the main body casing and configured to rotate about an axis parallel to the first and second axes such that when the cover is opened, the belt is exposed through an opening formed in the main body casing;
• a first developer container containing black developer for developing an electrostatic latent image on the first photoconductor drum, and a second developer container containing color developer for developing an electrostatic latent image on the second photoconductor drum, the first developer container being located closer to the cover than the second developer container;
• a cleaning member configured to remove developer from the belt;
• and
• a waste toner box configured to store the developer removed by the cleaning member,
• wherein the waste toner box is integrally formed with the first developer container, and the waste toner box is disposed on the same side as the first and second developer containers with respect to the belt.
