Medium discharging device and image forming apparatus

A medium discharging device comprising:

• a medium stacking portion on which a medium having an image recorded thereon is to be stacked;
• a medium discharge member that discharges the medium to the medium stacking portion;
• and
• a moving mechanism that moves the medium discharge member and the medium, which is being discharged, in a medium width direction that is perpendicular to a medium conveyance direction, to adjust a stack position where the medium, which is being discharged, is to be stacked on the medium stacking portion, and
• that moves the medium discharge member only in a linear horizontal direction between an advanced position at a downstream end in the medium conveyance direction and a retracted position that is located upstream of the advanced position in the medium conveyance direction based on a discharging timing at which the medium is discharged from the medium discharge member.
