Estimating the term…
A two-cycle xerographic device having a multiple-roller magnetic brush developer which sequentially develops and then cleans the device's reusable photoconductor. The photoconductor provides one or more image panels for each revolution of the photoconductor. The photoconductor's interimage area, which separates the trailing edge of one panel from the leading edge of the same panel, or the leading edge of the next panel, is smaller (as measured in the direction of photoconductor movement) than the similar dimension spanned by the developer's spaced multiple rollers. As the panel's trailing edge leaves the first to-be-encountered roller, that roller's development electrode bias voltage is switched from a development to a cleaning bias. This switching function occurs sequentially, from one roller to the next, thus facilitating a small interimage area, and maximum photoconductor usage.
A two-cycle xerographic device having a reusable photoconductor with at least one image area and one interimage area thereon, and a plurality of xerographic facilities for performing the charging, imaging and transferring functions, said device including:
A method for sequentially developing and then cleaning a reusable photoconductor in a two-cycle xerographic process, by the use of a magnetic brush developer which first functions as a developer in the presence of a development bias, and then as a cleaner in the presence of a cleaning bias, the improvement comprising the steps of:
