摘要： An image forming apparatus, includes: a latent image carrier that carries an electrostatic latent image; a housing that stores toner inside; a toner carrier roller that is shaped approximately like a cylinder, is mounted to the housing rotatably about a rotational axis, rotates while carrying toner on a surface thereof to convey the toner to an opposed position facing the latent image carrier outside the housing, and is provided, on the surface thereof, with a plurality of convex sections which are regularly arranged in an axial direction parallel to the rotational axis and in a circumferential direction orthogonal to the axial direction and parallel to a circumferential surface of the toner carrier roller and a concave section which surrounds the convex sections; a seal member that is arranged in abutting contact with the surface of the toner carrier roller moving from the outside the housing toward the inside the housing at a position downstream of the opposed position in a rotation direction of the toner carrier roller to prevent toner leakage from the inside the housing; and a moving mechanism that relatively moves the toner carrier roller relative to the seal member in the axial direction.
