摘要： The toner of the present invention is characterized in that the charges rise up rapidly, the charge quantity is not insufficient nor excessive, the photoreceptor contamination is minimized and the toner is endurable under harsh conditions and against the high stress usage. The magnetic particle contained in the toner is of average particle size 0.01 μm through 0.50 μm, is of octahedron shape that is a convex polyhedron surrounded by eight triangles as a basis, each of vertexes and edges of the octahedron being in a curved surface shape and having a portion that can be taken as a straight line on the outer periphery of a projected image of said octahedron. The sphericity of the toner is 0.94 through 0.98. Here, the sphericity is defined by C2/C1, where C1 is a circumferential length of an image projected on a plane and C2 is a circumferential length of an assumed circle area as same as that of the projected image. Further, a number content of the toner of particle size 0.6 μm through 2.0 μm is smaller than 10%.

摘要： Magnetic toner involves magnetic powder 1 having the particle shape of an octahedron 2 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 making it difficult for charge-up to occur, 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.

摘要： The two component developer comprises magnetic toners and the magnetic carriers which forms magnetic ears on the surface of the developing roller. The magnetic toner is of an average particle size 0.01 μm through 0.50 μm and is of octahedron shape that is a convex polyhedron surrounded by eight triangles as a basis, each of the vertexes and edges of the octahedron shape toner being in a curved surface shape and having a portion that can be taken as a straight line on the outer periphery of a projected image of the octahedron shape toner. The magnetic ears are electrically charged by the friction between the magnetic toner and the magnetic carriers and the magnetic ears on the developing roller are carried to the electrostatic latent image on the photoreceptor. The latent image is developed by the magnetic toners in the magnetic ears, in a small gap between the developing roller and the photoreceptor. Due to the two component developer, the toner charges are rapidly induced and moreover the toners are not excessively charged.
