An image-forming apparatus includes: an image carrier; a latent
image-forming unit for forming a latent image on the image carrier; a
cleaning unit including a residue removal member a residue transport
member; a residue collecting unit having an receiving port adapted to be
able to connect to and be away from the ejecting port and to receive the
residue ejected from the ejection port; a shield member capable of
shifting between an ejection position and a shield position; and an
approach and separation mechanism that moves the latent image-forming
unit between an approach position where the latent image-forming unit
approaches the image carrier and a separate position where the latent
image-forming unit is separated from the image carrier, the approach and
separation mechanism allowing the latent image-forming unit to move to
the separation position as the shield member shifts to the shield
position.
