  • Patent number: 11971670
    Abstract: An image forming apparatus includes an intermediate transfer belt, an outer roller, a power source, and a regulation member. The outer roller transfers a toner image onto a recording material. The power source applies a voltage to the outer roller. The regulation member regulates orientation of the recording material. Information is acquired regarding a timing at which orientation of a recording material first portion, passing through the transfer portion that is located between the outer roller and the regulation member, can change to move closer to the intermediate transfer belt. Based on the acquired information, a transfer voltage target value for transfer onto the recording material is changed between a first target value of a period anterior to the timing and a second target value of a period posterior to the timing that is larger in absolute value than the first target value.
