Image forming unit and image forming apparatus using the same

An image forming apparatus comprising a unit-rotating member that supports a plurality of image forming units in a vertical plane rotatably, and forming images by shifting the plurality of image forming units sequentially to the image forming position, wherein the image forming unit comprises an image forming unit main body having an image forming means, and a handle provided at the image forming unit main body so that it is capable of taking a holdable posture in which a user can hold the handle and a non-holdable posture in which a user cannot hold the handle, and is urged toward the non-holdable posture constantly by its elasticity.

An image forming apparatus comprising a unit-rotating member that supports a plurality of image forming units in a vertical plane rotatably, and forming images by shifting the plurality of image forming units sequentially to the image forming position, wherein the image forming unit comprises an image forming unit main body, a photosensitive member exposed to the outer periphery of the rotation surface of the image forming unit main body, a handle provided at the image forming unit main body, and the handle of the image forming unit at the position where the image forming unit is replaced with a new unit in the unit-rotating member, is arranged farther from a front side of the image forming apparatus than the photosensitive member.

An image forming apparatus comprising a unit-rotating member that supports a plurality of image forming units in a vertical plane rotatably, and forming images by shifting the plurality of image forming units sequentially to the image forming position, wherein the image forming unit comprises a photosensitive member unit that supports the photosensitive member, a developing unit that supports the developing device, and a handle;
