Image forming apparatus having intermediate transfer bodies, brush roller devices and transfer roll device having defined axial lengths

An image forming apparatus comprising:

• at least one image bearing body having a photosensitive layer on the surface thereof, a toner image as defined by image information able to be formed on said photosensitive layer;
• an intermediate transfer device having at least one intermediate transfer body to which at least one toner image is transferred from said at least one image bearing body;
• a transfer roll device for transferring the at least one toner image from one of the at least one intermediate transfer body of the intermediate transfer device onto a recording sheet;
• at least one brush roll device for removing residual toner from the at least one intermediate transfer body of the intermediate transfer device;
• and
• a toner collecting device for collecting the toner attached to the surface of said transfer roll device;
• wherein an axial length of each said at least one intermediate transfer body is longer than that of at least one of said at least one brush roll device, the axial length of said transfer roll device is longer than that of each said at least one intermediate transfer body, and the axial length of said toner collecting device is longer than that of each said at least one intermediate transfer body.
