图像形成设备
摘要：
本发明公开了图像形成设备，该图像形成设备包括：用于承载静电潜像的图像承载部件；用于容纳显影剂的显影容器；包含第一电极部件的用于承载显影容器中容纳的显影剂以显影静电潜像的显影剂承载部件；包含第二电极部件和围绕第二电极部件设置的泡沫层的用于通过旋转与显影剂承载部件接触地将显影容器中容纳的显影剂供给到显影剂承载部件的显影剂供给部件；用于测量要形成的图像的打印像素数的测量部；用于在图像形成之后基于测量的打印像素数执行用于将显影剂供给到显影剂供给部件的供给操作的供给设备；和用于通过在供给设备的供给操作之后检测第一电极部件和第二电极部件之间的静电容量检测显影容器中容纳的显影剂的检测设备。
摘要（英）：

An image forming apparatus includes an image bearing member for bearing an electrostatic latent image; a developing container; a developer carrying member, including a first electrode member, for carrying the developer contained in the developing container to develop the latent image; a developer supplying member, including a second electrode member, for supplying the developer contained in the developing container to the developer carrying member by rotation in contact with the developer carrying member; a measuring portion for measuring a pixel number of an image to be formed; a supplying device for supplying the developer to the developer supplying member on the basis of a measured pixel number after image formation; and a detecting device for detecting an amount of the developer contained in the developing container by detecting electrostatic capacity between the first and second electrode members after the supplying operation.
