Abstract:
A magnetic toner is provided, which has a magnetic toner particle containing a binder resin, a wax, and a magnetic body, wherein, when Dn is a number-average particle diameter of the toner, CV 1  is coefficient of variation of a brightness variance value of the toner in a particle diameter range of Dn−0.500 to +0.500, and CV 2  is coefficient of variation of a brightness variance value of the toner in a particle diameter range of Dn−1.500 to −0.500, a relationship CV 2 /CV 1  1.00 is satisfied; an average brightness of the toner in the range of Dn−0.500 to +0.500 is 30.0 to 60.0; and when, in a cross section of the toner observed using a transmission electron microscope, which is divided with a square grid having a side of 0.8 μm, coefficient of variation CV 3  of an occupied area percentage for the magnetic body is 40.0 to 80.0%.

Claim (Index 9):
An image-forming method comprising:\n a charging step of charging an electrostatic latent image bearing member by applying voltage from the exterior to a charging member; a latent image-forming step of forming an electrostatic latent image on the charged electrostatic latent image bearing member; a developing step of developing the electrostatic latent image with a toner carried on a toner bearing member to form a toner image on the electrostatic latent image bearing member; a transfer step of transferring, by using an intermediate transfer member or without using an intermediate transfer member, the toner image on the electrostatic latent image bearing member to a transfer material; and a fixing step of fixing, by using a means for applying heat and pressure, the toner image that has been transferred to the transfer material, wherein the developing step is based on a mono-component contact developing system in which development is carried out by direct contact of the electrostatic latent image bearing member with the toner carried on the toner bearing member; and the toner is a magnetic toner comprising a magnetic toner particle containing a binder resin, a wax, and a magnetic body, and wherein, when Dn (\u03bcm) is a number-average particle diameter of the magnetic toner, CV 1  (%) is coefficient of variation of a brightness variance value of the magnetic toner in a particle diameter range from at least Dn\u22120.500 to not more than DN+0.500, and CV 2  (%) is coefficient of variation of the brightness variance value of the magnetic toner in a particle diameter range from at least Dn\u22121.500 to not more than Dn\u22120.500, the CV 1  and the CV 2  satisfy a relationship in formula (1) below, an average brightness of the magnetic toner in the particle diameter range from at least Dn\u22120.500 to not more than DN+0.500 is at least 30.0 and not more than 60.0, and when, in a cross section of the magnetic toner observed using a transmission electron microscope, the cross section of the magnetic toner is divided with a square grid having a side of 0.8 \u03bcm, coefficient of variation CV 3  of an occupied area percentage for the magnetic body is at least 40.0% and not more than 80.0%:\n CV 2/ CV 1\u22641.00 \u2003\u2003(1).
