1. An image forming apparatus comprising:
an image bearing member configured to bear a toner image;
a transfer device configured to transfer the toner image from the image bearing member to a recording material;
an applying portion configured to apply a voltage to the transfer device;
a detecting portion configured to detect density information on a density of an image on the recording material onto which the image is transferred by the transfer device;
a controller configured to execute an operation in a setting mode in which during non-image formation, a plurality of test images are transferred onto the recording material under application of different test voltages to the transfer device and then a transfer voltage applied to the transfer device during image formation is set on the basis of a detection result of the test images transferred onto the recording material as detected by the detecting portion; and
a receiving portion configured to receive instruction information,
wherein in a case that the operation in the setting mode is executed to set the transfer voltage for a one-side mode in which an image is formed on one side of a predetermined recording material, the receiving portion is capable of receiving the instruction information selectively instructing a mode to be executed from a plurality of modes including a first setting mode in which the transfer voltage is set so that the transfer voltage set in the setting mode satisfies a first predetermined condition and a second setting mode in which the transfer voltage is set so that the transfer voltage set in the setting mode satisfies a second predetermined condition different from the first predetermined condition,
wherein the test images include a plurality of first test images having a first density on the image bearing member and a plurality of second test images having a second density on the image bearing member, the second density being higher than the first density, and
wherein the first predetermined condition includes a first condition regarding the plurality of first test images and the second predetermined condition includes a second condition regarding the plurality of first test images and being different from the first condition.
