10. A method of developing an image in an image forming apparatus, the method comprising:
developing a latent image on a latent image bearer with developer borne on a developer bearer of a developing device in an attaching and detaching unit;
attaching an attached and detached section including the latent image bearer to the attaching and detaching unit;
contacting a main reference portion to a main reference part of the attaching and detaching unit to position the attaching and detaching unit;
contacting a sub-reference portion to a sub-reference part of the attaching and detaching unit to receive a rotation of the attaching and detaching unit around the main reference part;
pressing a pressing member configured against the attaching and detaching unit to generate a biasing force biasing the developer bearer toward the latent image bearer and a rotational moment toward the sub-reference portion of the attached and detached section around the main reference part with respect to the attaching and detaching unit,
wherein pressure of the pressing member against the attaching and detaching unit includes a force component generating the rotation moment and a force component parallel to a surface of the sub-reference portion, and
wherein the force component parallel to the surface of the sub-reference portion is larger than the force component generating the rotation moment.
