Abstract

A recording-material-transporting device includes an attracting part to which a recording material is attracted from below, and a blowing device that blows air from a position higher than the attracting part to an edge of the recording material attracted to the attracting part.

First claim

What is claimed is:

1 . A recording-material-transporting device comprising:
an attracting part to which a recording material is attracted from below; and a blowing device that blows air from a position higher than the attracting part to an edge of the recording material attracted to the attracting part.

2 . The recording-material-transporting device according to claim 1 ,
wherein the blowing device blows air to the edge by sending air obliquely downward from the position higher than the attracting part, the position being away from the edge.

3 . The recording-material-transporting device according to claim 1 ,
wherein the air to be blown to the edge from the position higher than the attracting part is first directed upward from a position lower than the attracting part to the position higher than the attracting part and is redirected downward.

4 . The recording-material-transporting device according to claim 3 , further comprising:
an air guiding part that guides the air directed to the position higher than the attracting part, wherein the air directed upward is guided downward by the air guiding part.

5 . The recording-material-transporting device according to claim 4 , further comprising:
a rugged part against which the recording material attracted to the attracting part is pressed such that the edge of the recording material is made to have a wavy shape, wherein the air guiding part is included in a member having the rugged part.

6 . The recording-material-transporting device according to claim 4 ,
wherein a lower surface of a member included in the recording-material-transporting device is used in causing the air directed upward to the position higher than the attracting part to be guided downward.

7 . The recording-material-transporting device according to claim 6 ,
wherein the lower surface includes a slope descending from a side farther from the edge of the recording material toward a side nearer to the edge such that the air directed downward flows toward the edge.

8 . The recording-material-transporting device according to claim 7 ,
wherein the lower surface includes a guiding part on a side farther from the edge than the slope, and wherein the air directed to the position higher than the attracting part is guided by the guiding part toward the slope.

9 . The recording-material-transporting device according to claim 1 , further comprising:
an air guiding part that guides the air directed to the position higher than the attracting part, wherein the air guiding part has a recess that is concave upward, and wherein the air directed upward to the position higher than the attracting part is guided by an inner surface of the recess in such a manner as to be blown downward to the edge.

10 . The recording-material-transporting device according to claim 9 ,
wherein the inner surface of the recess is concave upward and is curved in such a manner as to form an arc in sectional view.

11 . The recording-material-transporting device according to claim 9 , further comprising:
a counter member that faces the inner surface of the recess while being spaced apart from the inner surface.

12 . The recording-material-transporting device according to claim 1 ,
wherein the air from the position higher than the attracting part is blown to a wavy part of the edge.

13 . The recording-material-transporting device according to claim 9 , further comprising:
a discharge port from which the air to be directed toward the recess of the air guiding part is discharged, wherein a width of the recess in a direction in which the edge extends is greater than or equal to a width of the discharge port in the direction in which the edge extends.

14 . A recording-material-transporting device comprising:
an attracting part to which a recording material is attracted from below; and a blowing device that blows air to an edge of the recording material attracted to the attracting part, the air being blown from a position higher than the edge.

15 . A recording-material-transporting device comprising:
an attracting part to which a recording material to be transported in one direction is attracted from below; a recording-material-meeting surface positioned on a downstream side with respect to the attracting part in the one direction and facing downward such that a part of the recording-material-meeting surface meets the recording material attracted to the attracting part; and an air sending unit provided at a position lower than the attracting part, wherein the recording-material-meeting surface include a rugged surface, and wherein the recording-material-meeting surface intersects an extension line extending in a direction in which the air sending unit sends air.

16 . The recording-material-transporting device according to claim 15 ,
wherein the rugged surface includes ridges that are arranged in bilateral symmetry when seen from the downstream side in the one direction.

17 . An image forming apparatus comprising:
an image forming device that forms an image on a recording material; and a recording-material-transporting device that transports the recording material, wherein the recording-material-transporting device includes the recording-material-transporting device according to claim 1 .
