An image forming apparatus is provided. The image forming apparatus includes an image forming unit, a door to cover an opening in a chassis, a fixing unit, a frame, a linear motion member to linearly move along with the door, a guiding member to guide the linear motion member to move linearly, a coupler assembly to couple the door with the linear motion member and move the linear motion member, and a manipulation member being movable according to movement of the linear motion member. The linear motion member includes a contact portion, with which the manipulation member comes in contact along an intersecting direction. The guiding member includes a slider plane to slidably support the linear motion member. The linear motion member is slidably supported by the slider plane of the guiding member at a surface which is on an opposite side from the surface having the contact portion.
