Abstract
An image forming apparatus includes a photoconductive drum, a developing roller, a humidity sensor configured to detect a humidity, and a controller configured to execute a single-side printing, a first-double-side printing and a second double-side printing. The controller is configured to execute the first double-side printing in which images are printed at a first developing-bias voltage on both the first surface and the second surface of the sheet when the humidity detected by the humidity sensor is greater than a threshold value. The controller is configured to execute the second double-side printing in which an image is printed at a second developing-bias voltage, which is less than the first developing-bias voltage, on the second surface of the sheet when the humidity detected by the humidity sensor is equal to or less than the threshold value.
