An image forming apparatus includes an image forming portion that forms an image on a first image bearing member, a transfer member that transfers the image on the first image bearing member to a second image bearing member, a power supply, a detecting portion that detects a voltage value and a current value, a velocity changing portion, an environment detecting portion, and a controller that determines a transfer voltage value in transferring an image based on a result detected at the detecting portion. An image can be formed at the plurality of velocities. The controller determines a transfer voltage value at a velocity other than the plurality of velocities based on a result detected at the detecting portion and a result detected at the environment detecting portion when the first image bearing member is operated at a predetermined velocity.
