Abstract
A color printer 1 has a rotary type developing device 30 which rotated by an input gear 46 that receives power from a motor, and a plurality of developing units 13 supported on a frame 28. The plurality of developing units 13 accommodates toner of different colors therein. The frame 28 a first annular gear 29 being configured to be rotated by the input gear 46, and a second ring-shaped annular member 32 having a larger external diameter than the first annular gear 29. The second ring-shaped annular member 32 is disposed adjacent to and on the outer side of said first annular gear and on the same rotational axis.
Claims18
A rotary type developing device that receives a force from an input gear member that is rotated by gear train that receives a motive force from a drive source provided in a color image forming device, the rotary developing device comprising:
- a plurality of containers being configured to accommodate respectively and internally developers of different colors;
- and
- a support member including a support having
- a rotating shaft being configured to support said plurality of containers,
- a first annular gear being configured to be rotated by the input gear member, and
- a second ring-shaped annular member having a larger external diameter than said first annular gear, and being disposed adjacent to and on the outer side of said first annular gear and on the same rotational axis.
An image forming apparatus comprising:
- an image support member having a surface, an electrostatic latent image being configured to be formed thereon;
- a gear train;
- an input gear member having a plurality of teeth being configured to be rotated by said gear train;
- and
- rotary type developing device being configured to receive a force from said input gear and being arranged to supply toner to said photosensitive drum, said rotary type developing device having
- a plurality of containers being configured to accommodate respectively and internally developers of different colors, and
- a support member including a support having
- a rotating shaft being configured to support said plurality of containers,
- a first annular gear being configured to be rotated by said input gear member, and
- a second ring-shaped annular member having a larger external diameter than said first annular gear, and being disposed adjacent to and on the outer side of said first annular gear and on the same rotational axis.
