Abstract
An image forming apparatus may include first, second, third, and fourth photosensitive media; a first driving source to rotate the first photosensitive medium; a second driving source to rotate the second photosensitive medium; and a planetary gear train to receive rotational forces of the first and second driving sources so as to rotate the third photosensitive medium, wherein the fourth photosensitive medium is rotated by being linked with the third photosensitive medium.
Claims12
An image forming apparatus comprising:
- first, second, third, and fourth photosensitive media;
- a first driving source to rotate the first photosensitive medium;
- a second driving source to rotate the second photosensitive medium;
- and
- a planetary gear train to receive rotational forces of the first and second driving sources so as to rotate the third photosensitive medium,
- wherein the fourth photosensitive medium is rotated by being linked with the third photosensitive medium, and
- wherein powers of the first and second driving sources are synthesized by the planetary gear train, and are transmitted to the third photosensitive medium so that the third photosensitive medium is rotated.
4 more elements
An image forming apparatus comprising:
- a plurality of photosensitive media;
- and
- a planetary gear train to receive rotational forces of a first driving source and a second driving source so as to rotate one of the photosensitive mediums,
- wherein at least one other photosensitive medium is rotated by being linked with the one of the photosensitive mediums, and
- wherein powers of the first and second driving sources are synthesized by the planetary gear train, and are transmitted to the at least one other photosensitive medium so that the at least one other photosensitive medium is rotated.
