1. An image forming apparatus for forming a toner image on a recording material, comprising:
an image forming portion for forming the toner image, formed with toners of a plurality of colors, on an intermediary transfer member; a transfer member for forming a transfer nip in contact and cooperation with the intermediary transfer member, said transfer member transferring the toner image from the intermediary transfer member onto the recording material while feeding the recording material in the transfer nip; a fixing portion for fixing the toner image on the recording material by heating the recording material on which the toner image is transferred while feeding the recording material in a fixing nip, said fixing portion including a heating member and a pressing member for forming the fixing nip in cooperation with the heating member; and a cleaning member for cleaning a surface of the intermediary transfer member in contact with the intermediary transfer member, said cleaning member being provided between said image forming portion and the transfer nip with respect to a movement direction of the intermediary transfer member, wherein toner particles of each of the toners contain a binder resin and a wax which is contained in an amount of 3 weight parts or more per 100 weight parts of the binder resin, wherein said image forming apparatus at least includes a first toner container containing a first formulation toner in which the wax is only a hydrocarbon wax or a mixture of the hydrocarbon wax and a wax other than the hydrocarbon wax which is contained in a larger amount than the wax and includes a second toner container containing a second formulation toner in which the wax is only an ester wax or a mixture of the ester wax and a wax other than the ester wax which is contained in a large amount than the wax, wherein said image forming apparatus is capable of executing an image forming operation for forming the toner image on the intermediary transfer member at said image forming portion to form the toner image on the recording material, and is capable of executing an operation in a toner supplying mode for supplying the toner or the toners to the intermediary transfer member at said image forming portion to dispose the toner or the toners between said cleaning member and the intermediary transfer member at predetermined timing when the image forming operation is not performed, and wherein said image forming apparatus is capable of executing the operation in the toner supplying mode in which only the first formulation toner is used or a mixture of the first formulation toner and the second formulation toner is used so that the first formulation toner is used in a larger amount than the second formulation toner. |
