TONER AND IMAGE FORMING METHOD
摘要:
Toner for electrostatic charge development wherein no scumming occurs, and toner leakage caused by charge defect of the toner on a developing roller can be inhibited, and an excellent image stability is obtained is provided.The toner used for an image forming method having a latent electrostatic image forming step of forming a latent electrostatic image on a latent electrostatic image bearing member primarily charged, a developing step of developing the latent electrostatic image by each toner which multiple developing devices have to form a toner image on the latent electrostatic image bearing member, a transferring step of transferring the toner image with respective colors formed on the latent electrostatic image bearing member onto a recording material and a fixing step of fixing the toner image transferred onto the recording material, wherein the toner comprises a colorant and a resin and contains an organic boron compound represented by a following chemical formula (A) as a charge controlling agent, further the toner is treated with an inorganic fine particle and at least one of the inorganic particles is a magnesium silicate compound represented by a following general formula [2] is provided. wherein X is an alkali metal, R1, R2, R3 or R4 each represents a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, or a halogen atom. MgxSiyO(x+2y) [2] wherein x and y are integers.
