Abstract:
1. An image forming apparatus comprising: a plurality of image bearing members having respective peripheral surfaces and arranged sequentially so that toner images of toners having different colors are formed on the peripheral surfaces, respectively; an endless belt having a surface and so rotated that the toner images formed on the image bearing members are sequentially transferred to the surface or a sheet conveyed on the surface; a plurality of transferring members for sandwiching the endless belt with the corresponding image bearing members to transfer the toner images formed on the image bearing members to the surface of the endless belt or the sheet; and wherein the image bearing member on the downstream-most side among the plurality of image bearing members and from which the toner image is last transferred to the surface of the endless belt or the sheet is so arranged that a contact pressure of the downstream-most side image bearing member against the endless belt becomes higher than contact pressures of the other image bearing members against the endless belt.
