Developing device accommodating apparatus and image forming apparatus and developing
device |
(57) An image forming apparatus includes an image bearing member (11), image forming station
for forming a latent image on the image bearing member, a conveying passage (104,
112) extending toward the image bearing member to guide a developing device (13),
a first moving mechanism for engaging with the developing device in the conveying
passage and moving it in a substantially horizontal plane, wherein the image bearing
member, the latent image forming station, the conveying passage that the first moving
mechanism are provided in a main body (103) of the image forming apparatus, a device
(150) for accommodating a plurality of developing devices (13A-D). The accommodating
device is mounted to the main body, the accommodating device includes, a second moving
mechanism for moving the developing device opposed to the conveying passage into the
conveying passage in a substantially horizontal plane and an accommodating case having
partition stages (151a-d) arranged substantially vertically for accommodating plural
developing devices and movable together with the developing devices accommodated
therein, and a driver for transmitting a driving force selectiveIy to the first driving
mechanism, the second driving mechanism and the accommodating case.
