Abstract
An image forming apparatus includes a plurality of image forming units. A first image forming unit includes a first image carrier, a first developer carrier that is applied with a first developing voltage, and a first layer-forming member that is applied with a first layer-forming voltage having the same polarity as polarity of the first developing voltage. The second image forming unit includes a second image carrier, a second developer carrier that is applied with a second developing voltage, and a second layer-forming member that is applied with a second layer-forming voltage having the same polarity as polarity of the second developing voltage. An absolute value of the first layer-forming voltage is smaller than an absolute value of the first developing voltage. An absolute value of the second layer-forming voltage is greater than an absolute value of the second developing voltage.
