摘要： The present invention concerns controlling a potential used to form an electrostatic image for image formation. According to the invention, an electrostatic latent image is formed on an image bearing member using, for example, a potential stored in a memory. The potential of the latent image is detected, and if the potential is not within a specified range, the potential is controlled (i.e., changed) to form another latent image with the changed potential. The latent image is then developed and the density of the developed image detected. In one embodiment, the amount of developer to be replenished is then controlled based upon the detected density and a target potential value, where the target potential value is determined and set based on the detected density and the potential used in the potential controlling step. In a related embodiment, when a result of the potential obtained after termination of a normal image formation process is out of a designated range, potential control is performed after termination of a next normal image formation process.
摘要翻译：本发明涉及控制用于形成用于图像形成的静电图像的电位。根据本发明，使用例如存储在存储器中的电位，在图像承载部件上形成静电潜像。检测潜像的电位，如果电位不在规定范围内，则电位被控制（即改变），形成具有变化的电位的另一潜像。然后显影潜像，并检测显影图像的浓度。在一个实施例中，然后基于检测到的密度和目标电位值来控制要补充的显影剂的量，其中基于检测到的浓度和在电势控制步骤中使用的电位来确定和设定目标电势值。在相关实施例中，当在正常图像形成处理结束之后获得的电位的结果超出指定范围时，在下一个正常图像形成处理结束之后执行电位控制。
