Abstract
A rotary developing device 30 is provided in an image forming device that is rotated by an input gear 46. The rotary developing device 30 has a plurality of developing units 13, a frame 28, and a rotation stop mechanism 50. Each of the plurality of developing units 13 house toner of one of the colors, and develops at a predetermined developing position. The frame 28 includes a support portion 36 that supports the plurality of developing units 13 and has a rotation shaft, and a ring shaped gear 29 that is rotated by the input gear 46. The rotation stop mechanism 50 stops the rotation of the frame 28 at the developing position. Also, the number of gear teeth in the ring shaped gear 29 is the number of gear teeth in the input gear 46 multiplied by the number of developers.
Claims22
A rotary developing device provided in an image forming device that is rotated by an input gear member to which motive force is input from a drive source, comprising:
- a plurality of containers being configured to house individually a color developer configured to develop at a plurality of respective developing positions;
- a support portion having a rotation shaft being configured to support said plurality of containers;
- a support member having a ring shaped gear being configured to be rotated by the input gear member, a number of gear teeth in said ring shaped gear being a number of gear teeth in the input gear multiplied by the number of said plurality of containers;
- and
- a rotation stop mechanism having
- a first latching member being fitted to said input gear member,
- a second latching member being configured to latch with said first latching member, and
- a second latching member drive mechanism being connected to said second latching member that drives said second latching member to latch and to unlatch said second latching member and said first latching member.
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 image support member, said rotary type developing device having
- a plurality of containers being configured to house individually a color developer configured to develop at a plurality of respective developing positions,
- a support portion having a rotation shaft being configured to support said plurality of containers,
- a support member having a ring shaped gear being configured to be rotated by the input gear member, and
- a rotation stop mechanism being configured to stop the rotation of said support member at each of said plurality of developing positions, said rotation stop mechanism having
- a first latching member being fitted to said input gear member,
- a second latching member being configured to latch with said first latching member, and
- a second latching member drive mechanism being connected to said second latching member that drives said second latching member to latch and to unlatch said second latching member and said first latching member.
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;
- rotary type developing device being configured to receive a force from said input gear and being arranged to supply toner to said image support member, said rotary type developing device having
- a plurality of containers being configured to house individually a color developer configured to develop at a plurality of respective developing positions,
- a support portion having a rotation shaft being configured to support said plurality of containers,
- a support member having a ring shaped gear being configured to be rotated by the input gear member, a number of gear teeth in said ring shaped gear being a number of gear teeth in the input gear multiplied by the number of said plurality of containers, and
- a rotation stop mechanism being configured to stop selectively said support member at one of said plurality of respective developing positions and a standby position, said rotation stop mechanism having
- a first latching member being fitted to said input gear member,
- a second latching member being configured to latch with said first latching member, and
- a second latching member drive mechanism being connected to said second latching member that drives said second latching member to latch and to unlatch said second latching member and said first latching member.
