Image forming apparatus

An image forming apparatus, comprising:

• a housing;
• a flapper configured to be swingable with respect to the housing on a swing track and movable between a first position and a second position on the swing track;
• a pressure link configured to be swingable with respect to the housing and the flapper, the pressure link being coupled to the flapper;
• a first contact surface arranged on the housing, the first contact surface being configured to contact the flapper and restrict the flapper from moving beyond the second position;
• a first urging member arranged between the pressure link and the flapper, the first urging member being configured to urge the flapper to swing with respect to the pressure link toward the first contact surface;
• a second urging member arranged between the housing and the pressure link, the second urging member being configured to urge the pressure link to act on the flapper to tend toward staying in the first position;
• and
• a flapper switcher comprising a pressure applier, the pressure applier being configured to move between a pressing position, in which the pressure applier presses the pressure link, and a separated position, in which the pressure applier is separated from the pressure link,
• wherein the flapper is swingable with respect to the pressure link against an urging force from the first urging member, after the pressure applier presses the pressure link to move the flapper from the first position to the second position against an urging force from the second urging member and when the flapper being moved contacts the first contact surface.
