Image forming apparatus

An image forming apparatus, comprising:

• an endless and movable image bearing belt that bears a toner image;
• an endless and movable transfer material bearing belt that bears and conveys transfer material;
• a first tension member configured to supply a tension to said transfer material bearing belt member;
• a second tension member configured to supply a tension to said transfer material bearing belt member, wherein said second tension member being arranged downstream of the first tension member in a moving direction of the transfer material bearing belt;
• a transfer member arranged on an inner surface side of the transfer material bearing belt between said first tension member and said second tension member to transfer the toner image from said image bearing belt to the transfer material borne on the transfer material bearing belt;
• an opposing member configured to supply a tension to the image bearing belt, the opposing member nipping the image bearing belt and the transfer material bearing belt together with the transfer member;
• and
• a belt guide member arranged on an inner surface side of the transfer material bearing belt between the first tension member and the transfer member to guide movement of the transfer member bearing belt,
• wherein a conveyance direction of the transfer material in a first area is substantially the same as a conveyance direction of the transfer material in a second area, the first area corresponding to a nip area formed by the opposing member and the transfer member and the second area corresponding to an area in which the belt guide member bringing the transfer material bearing belt and the image bearing belt come into contact with each other.
