摘要： An image forming apparatus forms images. A developer bearing body receives a first voltage and supplies developer to the electrostatic latent image formed on an image bearing body. A supplying member receives a second voltage and supplies the developer to said developer bearing body. A detector detects at least one of an environmental condition, e.g., temperature and humidity outside of an apparatus and an environmental condition e.g., temperature inside of the apparatus. A controller controls the difference between the first voltage and the second voltage in accordance the environmental conditions. The controller makes a decision to determine whether the outside temperature is not lower than a first reference, whether outside humidity is not higher than a second reference, and whether inside temperature is not lower than a third reference. If the above criteria are met, the controller decreases the absolute value of the difference.
