IMAGE FORMATION UNIT AND IMAGE FORMATION DEVICE

To provide an image formation unit and an image formation device which reduce a load applied on an image holder by making a buffer material absorb a load applied to a developer storage part during drop impact compared to a configuration not including a control part provided outermost a developing device so as to control rotation of the developing device by contacting with the buffer material.SOLUTION: An image formation unit held in a state to be stored in a flexible bag body and in a manner to make a buffer material buffer impact includes: an image holder in which an electrostatic latent image is formed; a developing device including developing means which contacts with the electrostatic latent image while rotating around the rotational center toward the image holder, so as to develop the electrostatic latent image; a developer storage part for storing a developer used by the developing device; and a control part which is provided outermost the developing device and which contacts with the buffer material so as to control the rotation of the developing device.SELECTED DRAWING: Figure 6 【課題】現像装置の最外郭に配置され緩衝材と接触して現像装置の回転を規制する規制部を備えていない構成に比べて、落下衝撃時に現像剤収容部にかかる荷重が緩衝材で吸収され、像保持体に加わる荷重を低減する。【解決手段】可撓性を有する袋体に収容された状態で緩衝材で衝撃を緩衝するように保持される像形成ユニットであって、静電潜像が形成される像保持体と、回転中心で像保持体に向かって回転しながら当接して静電潜像を現像する現像手段を有する現像装置と、現像装置で用いられる現像剤を収容する現像剤収容部と、現像装置の最外郭に配置され緩衝材と接触して現像装置の回転を規制する規制部と、を備えた。【選択図】図６
