Claims

[Claims for Utility Model Registration] (1) A rotatable photoreceptor, a cleaning means for removing residual toner on the photoreceptor, and a collection container for the toner removed thereby are integrated into the main body of the image forming apparatus. In the photoconductor unit configured as a unit that can be attached to and detached from the photoconductor unit, the cleaning means and the toner collection container constitute a cleaning device that is integrally detachable from the photoconductor unit, and the cleaning device is configured to be detachable from the photoconductor unit. A photoconductor unit characterized by being provided with a device mounting section. (2) The above-mentioned cleaning device mounting portion has a seal on the upstream side in the photoconductor running direction of the cleaning means of the cleaning device to be mounted, the tip of which touches or approaches the photoconductor surface. A photoreceptor unit according to scope 1. (3) The photoreceptor unit according to claim 1, wherein the cleaning device has a shorter service life than the photoreceptor. (4) The photoconductor unit according to claim 3, wherein the cleaning device has a service life of not more than 2/3 of the photoconductor. (5) The above-mentioned cleaning device is characterized in that the amount of toner collected during the service life of the cleaning means and the capacity of the toner collection container are approximately equal to each other. Photoreceptor unit as described. (6) The photoreceptor unit according to claim 1, wherein the cleaning device has means for detecting whether the toner collection container is full. (7) The above-mentioned cleaning device is characterized in that it has a seal member that closes or reduces the opening in cooperation with the cleaning means when the photoconductor unit is removed from the photoconductor unit. Photoreceptor unit as described.
