Image forming apparatus having residual toner collecting containers

An image forming apparatus comprising:

• an image forming portion including an image bearing member for bearing a toner image and configured to form the toner image;
• an intermediary transfer belt provided below the image bearing member and onto which the toner image is transferred from said image bearing member;
• a first collecting container provided detachably and configured to collect residual toner discharged from said image forming portion;
• a second collecting container provided detachably and configured to collect the residual toner discharged from said image forming portion;
• a feeding device configured to feed the residual toner, discharged from said image forming portion, toward said first collecting container and said second collecting container selectively;
• and
• a cassette configured to accommodate a recording material,
• wherein said first collecting container and said second collecting container are provided below a bottom surface of said intermediary transfer belt and above said cassette and are disposed side by side in a widthwise direction perpendicular to a rotational axis direction of said image bearing member, and
• wherein at least a part of said first collecting container overlaps with said intermediary transfer belt and said cassette as viewed in the vertical direction, and at least a part of said second collecting container overlaps with said intermediary transfer belt and said cassette as viewed in the vertical direction.
