Abstract

<p>Organic photoconductor (OPC) has been steadily improving in printing speed and product life since launched in the 1980s. Today, OPC is used without replacement in some office machines. In the case of the industrial printing, it is necessary to minimize the machine maintenance time caused by OPC damage for cost saving. Therefore, it is strongly required from the market that OPC has high durability and long product life time. The function of OPC has developed as an electronic device that requires various functional characteristics such as sensitivity, speed responsiveness, mechanical strength, surface physical properties, and so on. The environment in which OPC is used is not so good compared with other electronic devices. Therefore, it is impossible to drastically prolong the life of OPC by simply improving electrical performance. Konica Minolta collected and sorted the customer environment and failure information worldwide. We have developed technologies for occurring and predicted faults and applied them to products.</p>
