Information processing system and non-transitory computer readable medium

A non-transitory computer readable medium storing a program causing a computer to execute a process for information processing, the process comprising:

• calculating a correction coefficient based on a voltage measurement value of a primary transfer unit in a first state in which voltages of same polarity are applied to the primary transfer unit and a secondary transfer unit in contact with an intermediate transfer belt of an image forming apparatus, and a voltage measurement value of the primary transfer unit in a second state in which voltages of opposite polarities are applied to the primary transfer unit and the secondary transfer unit, with a setting to make same current as in the first state flow through the primary transfer unit;
• and
• adjusting, using the correction coefficient, a transfer timing primary current to flow through the primary transfer unit when an image is transferred to an image recording medium.
