摘要： Magnetic toner involves magnetic powder 1 having the particle shape of an octahedron2 that is a convex polyhedron surrounded by eight triangles as a basis, each of the vertexes and edges of the octahedron being in a curved surface shape, and having a portion 3 that can be taken as a straight line on the outer periphery of its projected image. Therefore, the magnetic toner is superior in both two contradictory properties, that is, the property of making it easy for a charging amount to quickly rise as well as improving the charging amount and the property of preventing dielectric breakdown of the photosensitive layer of the amorphous silicon photoreceptor from occurring within a short period due to charge-up, thereby making it possible to form a good image under a wide environment. In an image forming method, an electrostatic latent image is developed into a toner image by a magnetic one-component jumping developing method using the magnetic toner.
