Abstract
In an image forming apparatus, an inertia roller having a large moment of inertia is arranged between a secondary transfer section and a primary transfer section, and in the neighborhood of the secondary transfer section. This configuration effectively reduces a velocity variation of an endless intermediate transfer belt that occurs when a printing medium enters the secondary transfer portion. Image defects are thus suppressed.
