Abstract:
1. An image forming apparatus comprising: a main body; a recording-medium accommodating section that is provided at the main body and that is configured to accommodate a recording medium having a surface; a feeding roller that is rotatable about an imaginary rotational axis extending in an axial direction and that is configured to be rotatingly driven in a rotational direction for feeding the recording medium to a conveying path; a supporting member having a first end that is swingably supported at the main body and a second end that is opposite to the first end and rotatably supports the feeding roller, the supporting member being swingable about an imaginary swing axis that is parallel to the imaginary rotational axis, the imaginary swing axis being located above the recording medium accommodated in the recording-medium accommodating section and being located upstream in a feeding direction of the recording medium with respect to the imaginary rotational axis; a first urging member that is configured to apply an urging force to the supporting member in such a manner that the feeding roller contacts the recording medium accommodated in the recording-medium accommodating section; a second urging member that is configured to urge the second end to assist the urging force of the first urging member when an angle between the surface of the recording medium accommodated in the recording-medium accommodating section and a plane containing both the imaginary rotational axis and the imaginary swing axis is smaller than a predetermined angle; and a contact part with which the second urging member selectively contacts as a result of movement of the supporting member, wherein the second urging member is configured to urge the second end to assist the urging force of the first urging member by contacting the contact part when the angle between the surface of the recording medium accommodated in the recording-medium accommodating section and the plane containing both the imaginary rotational axis and the imaginary swing axis is smaller than the predetermined angle.
