More Information
Summary:An image forming apparatus includes an image bearing member, a transfer member, a power source, a detecting portion, a controller, an environment detecting portion, and a contact member. In a case that an absolute water content acquired on the basis of environmental information is a predetermined threshold or more, the controller sets a limit voltage on the basis of a detection result of the detecting portion in a state in which the recording material is absent in a transfer portion, and the controller controls the power source so that an absolute value of a voltage applied from the power source to the transfer member during contact of the recording material with the transfer member and the contact member is an absolute value of the limit voltage or less.
