An apparatus for discharging bodily wastes has a receptacle for holding a person’s bodily waste products, including an upwardly facing opening for receiving the waste products. The gate oxide layer includes one of a gate oxide dip or a gate oxide undercut. Further, a talk-back channel is enabled to respond to communications received on the primary channel. The contact surface is configured to contact a charge-retentive surface of an electrophotographic imaging member so as to charge the charge-retentive surface.
