7. The medium transporting apparatus according to claim 2 , wherein the second guide portion includes a round corner with a curved surface that slopes downward from upstream to downstream and faces the second guide.

8. The medium transporting apparatus according to claim 7 , wherein the round corner is a first round corner; and

wherein the first guide portion includes a flat surface and a second round corner with a curved surface sloping downward from the flat surface.

9. The medium transporting apparatus according to claim 1 , wherein the second guide portion includes a plurality of cutouts aligned in the second direction.

10. The medium transporting apparatus according to claim 9 ,

wherein at least one second guide surface is defined between adjacent cutouts; and

wherein the first guide portion has a first dimension in the second direction, and the second guide portion has a second dimension in the first direction, the second dimension being larger than the first dimension.

11. The medium transporting apparatus according to claim 1 , wherein the second guide portion includes ridges and furrows disposed alternately so that each furrow is positioned between adjacent ridges.

12. The medium transporting apparatus according to claim 10 , wherein the at least one second guide surface includes a curved surface sloping downward in a direction substantially perpendicular to the first direction.

13. A medium transporting apparatus, comprising:

a first transporting section that transports a medium; and

a first guide for guiding the medium transported by the first transporting section, the first guide being disposed downstream of the first transporting section in a first direction in which the medium is transported;

wherein the first guide includes a first guide portion that extends in the first direction, and a second guide portion that extends in a second direction substantially perpendicular to the first direction;

wherein the second guide portion includes a plurality of cutouts aligned in the second direction;

wherein the first guide includes a first guide surface on which the medium is transported;

wherein at least one second guide surface is defined between adjacent cutouts;

wherein the first guide portion has a first dimension in the second direction, and the second guide portion has a second dimension in the first direction, the second dimension being larger than the first dimension;

wherein the first guide portion includes a first round corner with a first curved surface sloping downward from the first guide surface; and

wherein the at least one second guide surface includes a flat top surface and the second guide portion includes a second round corner with a second curved surface, the second curved surface being contiguous with the flat top surface and sloping downward from the flat top surface, the second curved surface having a larger radius of curvature than the first curved surface of the first round corner.

14. An image forming apparatus incorporating a medium transporting apparatus according to claim 1 .

15. The image forming apparatus according to claim 14 , further comprising:

a developing section for forming a developer image;

a transferring section for transferring the developer image onto a medium; and

a fixing section for fixing the developer image on the medium;

wherein the fixing section includes the first transporting section.

16. A medium transporting apparatus, comprising:

a first transporting section that transports a medium;

a first guide for guiding the medium transported by the first transporting section, the first guide being disposed downstream of the first transporting section in a first direction in which the medium is transported;

wherein the first guide includes a first guide rib protruding from a base portion and extending in the first direction, and a second guide rib protruding from the base portion and extending in a second direction substantially perpendicular to the first direction;

wherein a guide surface of the first guide rib and a guide surface of the second guide rib are aligned on a same plane at an end portion of the first guide in the first direction;

wherein the second guide rib includes a plurality of ridges and furrows formed by upward inclinations and downward inclinations in the second direction;
