1. An image forming apparatus comprising:

  • an image bearing member configured to bear a toner image;

    an intermediate transfer member configured to be movable and to bear a toner image transferred from the image bearing member;

    a first transfer member configured to transfer the toner image from the intermediate transfer member to a recording material;

    a second transfer member, located in a downstream direction from the first transfer member, in which the intermediate transfer member is conveyed and is configured to transfer the toner image from the intermediate transfer member to the recording material;

    a voltage application unit configured to apply voltages to the first transfer member and the second transfer member to transfer the toner image from the intermediate transfer member to the recording material;

    an acquisition unit configured to acquire information associated with a moisture content;

    a control unit configured to individually control the voltage applied to the first transfer member and the voltage applied to the second transfer member, wherein the control unit includes a first function of controlling the voltage application unit such that a transfer current flowing through the second transfer member is less than a transfer current flowing through the first transfer member, and a second function of controlling the voltage application unit such that the transfer current flowing through the second transfer member is greater than the transfer current flowing through the first transfer member; and

    a process execution unit configured to execute an image forming process in a first image forming mode or a second image forming mode such that if the information acquired by the acquisition unit indicates a first moisture content for a recording material being conveyed the process execution unit executes the image forming process to form an image in the first image forming mode using the first function, wherein, if the information acquired by the acquisition unit indicates a second moisture content for the recording material less than the first moisture content, the process execution unit executes the image forming process to form an image in the second image forming mode using the second function.
