发明名称 Toner and image forming method
摘要 The objects of the present invention are to provide a toner excellent in transferability, little remaining on the photosensitive member and causing no defective image in roll-aided transfer (or at least such a phenomenon is well-controlled), and also to provide an image forming method using the same toner.The above objects are achieved when the toner contains a binder resin and colorant, inorganic fine particles, and a hydrotalcite compound shown by the formula:wherein 0<[X=(x1+x2+ . . . xk)]<=0.5; Y=(y1+y2+ . . . +yj)=1-X; j and k are each an integer of 2 or larger; M13+, M23+, . . . and Mj2+ are divalent metallic ions different from each other; L13+, L23+ . . . and Lk3+ are trivalent metallic ions different from each other; An- is a n-valent anion; and m>=0), and when the image forming method in which the above toner is used comprises a charging step which charges an image carrier; latent image forming step which forms an electrostatic latent image on the charged image carrier; developing step which develops the electrostatic latent image with a toner carried by a toner carrier, to form the toner image on the image carrier; transfer step which transfers the toner image on the image carrier to a medium through or not through an intermediate medium; and fixing step which fix the toner image on the medium.
