<p>An image forming apparatus includes a photoreceptor (11) having a first support shaft (11c) supported in a first frame body, a photosensitive portion (11a) supported by the first support shaft (11c), and a tapered portion (11b) having first tapered surfaces on both sides of the photosensitive portion (11a); a development roller (32) opposed to the photoreceptor and having a second support shaft (32b) rotatably supported by a second frame body, the development roller (32) being movable in a direction perpendicular to the second support shaft (32b) so as to approach and separate from the photoreceptor (11); roller members disposed on both sides of the development roller (32) coaxially with the second support shaft (32b), the roller member being movable in an axial direction of the second support shaft (32b) and including a second tapered surface which abuts against the first tapered surface; a moving member allowing the roller member to move on the second support shaft; and a biasing member biasing the development roller toward the photoreceptor (11).</p> |
