Transport device and image forming apparatus

An image forming apparatus, comprising:

• an image forming portion that forms an image on a recording medium;
• and
• a transport device that transports a recording medium on which an image is formed by the image forming portion or a recording medium on which an image has been formed by the image forming portion,
• wherein the transport device includes
• a first belt member movably stretched,
• a second belt member that is in contact with the first belt member to form a contact portion in cooperation with the first belt member, the second belt member being movably stretched,
• a first roller that stretches the first belt member and that is capable of adjusting a tilt in a longitudinal direction of the first roller,
• a second roller that stretches the second belt member and that is capable of adjusting a tilt in a longitudinal direction of the second roller,
• a third roller that stretches the first belt member and that is located adjacent to the first roller and upstream of the first roller in a movement direction of the first belt member,
• a fourth roller that stretches the first belt member and that is located adjacent to the first roller and downstream of the first roller in the movement direction of the first belt member,
• a fifth roller that stretches the second belt member and that is located adjacent to the second roller and upstream of the second roller in a movement direction of the second belt member,
• a sixth roller that stretches the second belt member and that is located adjacent to the second roller and downstream of the second roller in the movement direction of the second belt member, and
• a tension member that stretches the first belt member and that is located adjacent to the fourth roller and downstream of the fourth roller in the movement direction of the first belt member,
• wherein the third roller, the fourth roller, the fifth roller, and the sixth roller each have a uniform diameter in a longitudinal direction of the roller, and are disposed at positions other than the contact portion,
• wherein the third roller and the fourth roller are disposed at one side of the tension member.
