Toner collecting device, image forming unit and image forming apparatus
First Claim
1. A toner collecting device for conveying collected waste toner to a waste toner storing portion, comprising:
- a toner conveying means, said toner conveying means is positioned at a side opposite to a driveline included in an apparatus body to which said toner collecting device is mounted, said toner conveying means being directly driven by said driveline of said apparatus body;
a first waste toner scattering means configured to scatter the waste toner in said toner storing portion, the waste toner being conveyed to said waste toner storing portion by said toner conveying means; and
a second waste toner scattering means configured to scatter the waste toner in a direction opposite to said first waste toner scattering means, and said second waste toner scattering means is configured as a drive shaft for driving said toner conveying means,wherein a driveline for driving said toner conveying means is not arranged at said side opposite to said driveline of said apparatus body.

Abstract
In a toner collecting device of the present invention for conveying collected waste toner to a waste toner storing portion with a toner conveying device, the toner conveying device is positioned at a side opposite to a driveline included in an apparatus body to which the toner collecting device is mounted. A driveline for driving the toner conveying device is not arranged at the side opposite to the driveline of the apparatus body, but the toner conveying device is directly driven by the driveline of the apparatus body. With this configuration, the toner collecting device is capable of driving, e.g., a toner conveying belt or a toner conveying screw arranged at the counter drive side without sophisticating the configuration.
