the withdrawal holding mechanism holds separation of the second contact part from a movement track of the first contact part and the support member, when the support member moves from the displaced position to the image forming position.
9. The image forming apparatus according to claim 1 , wherein
the withdrawing mechanism includes at least
a slider that moves along with the first cover, and
a contact point holder that moves along with the slider, and brings the second contact part into contact with and separated away from the first contact part, and
the withdrawal holding mechanism includes at least
a second cover drive transmitting mechanism that moves along with movement of the second cover, and
a stopper that moves along with the second cover drive transmitting mechanism to hold and release the separation of the second contact part from the first contact part.
10. The image forming apparatus according to claim 9 , wherein
the slider includes a rib such that the slider moves, when the first cover is opened, in a first direction to push the contact point holder by the rib, in a direction in which the second contact part is withdrawn from the first contact part, and
the second cover drive transmitting mechanism moves, when the second cover is opened, the stopper toward the first contact part beyond the contact point holder.
11. The image forming apparatus according to claim 10 , wherein
the rib includes an inclined surface that comes into contact with the contact point holder, and
along with the movement of the slider in the first direction, the contact point holder moves along the inclined surface in a direction of separating the second contact part.
12. The image forming apparatus according to claim 10 ,
further comprising a biasing member that biases the stopper to the first contact part, wherein
the second cover drive transmitting mechanism includes a movement restricting part that restricts movement of the stopper to the first contact part in a state where the second cover is closed.
13. The image forming apparatus according to claim 6 , wherein
the first cover is provided on a front surface of the apparatus body,
the second cover is provided on a top surface of the apparatus body, and
the support member is movable between a front side of the apparatus body and the internal space in a state where the first cover is opened, and makes the image forming section attachable to and detachable from the support member in a state where the support member is pulled out to the front side of the apparatus body.
