Image forming apparatus including photoconductor drum and primary transfer roller

An image forming apparatus comprising:

• a photoconductor drum that carries an electrostatic latent image, which is developed into a toner image by application of toner;
• an intermediate transfer belt made to move in contact with the photoconductor drum;
• and
• a primary transfer roller opposed to the photoconductor drum via the intermediate transfer belt, and configured to press the intermediate transfer belt against the photoconductor drum, thereby transferring the toner image on the photoconductor drum, to the intermediate transfer belt from the photoconductor drum, the primary transfer roller being a metal roller,
• wherein a first contact region, being a region on the photoconductor drum in contact with the intermediate transfer belt, and a second contact region, being a region on the primary transfer roller in contact with the intermediate transfer belt, are kept from overlapping with each other, and
• a summit of the primary transfer roller, protruding farthest toward the photoconductor drum, in a direction in which the photoconductor drum and the primary transfer roller are aligned across the intermediate transfer belt, is set to intrude into a side where the photoreceptor drum is located, via the intermediate transfer belt.
