摘要：
In a rotary-type image forming apparatus, rotation of a rotary is temporarily stopped at a position where a coupling member and a drive transmission member are engageable with each other, and a developing roller is set in a rotating state. Subsequently, the rotary is rotated so as to bring the developing roller into contact with a surface of a photosensitive drum.
