A. The invention
The invention is a bottle which is intended to be used to
collect untransferred developer material obtained by cleaning
reproduction apparatus dielectric members. Prior art
collection bottles, typically made of polyethylene, experience
static charge buildup, which can cause arcing and electrical
interference and may present a shock hazard (Spec. at 1, line
33 to p. 2,
line 12). Appellants solve this problem by forming the
collection bottle of a conductive material, such as a carbon-
doped plastic. The embodiment shown in Figure 2 has a unitary
tab 52 for permitting the bottle to be connected to a grounded
support plate 56 by a screw 54. Alternatively, as shown in
Figure 4, the bottle can have a tab 52' located near the neck
for connecting the bottle to ground plate 56' by an extensible
cable 60, thereby permitting the bottle to be emptied without
disconnecting the ground connection (Spec. at 8, line 11 to p.
9, line 5). The carbon dopant is present in an amount which
produces a volume resistivity of less than 10 ohm-cms and8
preferably is present in amount of about 15-20% by weight to
