Abstract
An image forming apparatus comprises image forming sections for each color, each including a pressure receiving parts pair in a first outer region of a first rotary body and a second rotary body as an image carrier and a developing roller. A first image forming section includes a first pressure receiving part of the first rotary body and a second pressure receiving part of the second rotary body as the pressure receiving parts pair. A second image forming section includes a third pressure receiving part of the first rotary body and a fourth pressure receiving part of the second rotary body as the pressure receiving parts pair. A protruding distance of the first pressure receiving part is smaller than a protruding distance of the third pressure receiving part. A protruding distance of the second pressure receiving part is larger than a protruding distance of the fourth pressure receiving part.
