Drive means of an electro-photography process unit

A drive apparatus of an electro-photography process unit having a photo-sensitive drum, comprising:

• a drum drive gear mounted on a rotational shaft of said photo-sensitive drum, for driving said photo-sensitive drum;
• a magnet roll having a magnetic roll gear and located in a developer, for transferring toner to said photo-sensitive drum;
• a motor for providing rotary power;
• means for transferring said rotary power of said motor;
• first idle gear means for receiving said rotary power from said transfer means, said first idle gear means having a first idle gear engaged with said transfer means and a second idle gear coaxial with and spaced apart from said first idle gear, said second idle gear rotating in a same rotational direction as said first idle gear when said first gear is rotated by said transfer means, said second idle gear engaging said drum drive gear to rotate said drum drive gear;
• second idle gear means for engaging said first idle gear of said first idle gear means, and rotating in response to rotation of said first idle gear;
• first speed up gear means for engaging said second idle gear means, and rotating in response to said rotation of said second idle gear means;
• and
• second speed up gear means for engaging said first speed up gear means and said magnet roll gear, and for rotating said magnet roll gear in response to said rotation of said first speed up gear means.
