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: M1y1 <2+>M2y2 <2+> ... Mjyj <2+>L1x1 <3+>L2x2 <3+> ... Lkxk <3+)<OH)2.(X/n)A<n-> .mH2O wherein 0 < ÄX = (x1 + x2 + ... xk)Ü ≤ 0.5; Y = (y1 + y2 + ... + yj) = 1 - X; j and k are each an integer of 2 or larger; M1<3+>, M2<3+> ... and Mj<2+> are divalent metallic ions different from each other; L1<3+>, L2<3+> ... and Lk<3+> are trivalent metallic ions different from each other; A<n-> 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. <IMAGE>
