Abstract: A photosensitive drum is axially rotatable and has a surface on which an electrostatic latent image is formed. A developing device includes a development roller spaced from the photosensitive drum. The development roller includes a cylindrical sleeve and a coating layer, and the photosensitive drum includes a cylindrical tube and a functional layer. Each of the coating layer and functional layer is formed by dipping the sleeve or tube into a dipping bath with the sleeve or tube directed axially vertically. An axial end portion of the development roller that is lower during the dipping process is disposed opposite to an axial end portion of the photosensitive drum that is higher during the dipping process, and an axial end portion of the development roller that is higher during the dipping process is disposed opposite to an axial end portion of the photosensitive drum that is lower during the dipping process.

Abstract: A developing device includes a housing, a stirring member, a developing unit body, a driving device, a detecting device, and a control device. The housing accommodates developer supplied from a supply means and including toner and carrier. The stirring member rotates in the housing to stir the developer. The developing unit body rotates in the housing to convey the developer toward an image carrying member from the stirring member and attaches the toner to the image carrying member. The driving device rotationally drive at least one of the stirring member and the developing unit body. The detecting device detects the torque of the driving device. The control device performs a recovery process of controlling the supply means to supply at least one of the carrier and the developer to an interior of the housing when a detection result of the detecting device has a value lower than a threshold value.

Abstract translation: 显影装置包括壳体，搅拌构件，显影单元体，驱动装置，检测装置和控制装置。 壳体容纳从供给装置供应的显影剂，并且包括调色剂和载体。 搅拌构件在壳体中旋转以搅拌显影剂。 显影单元主体在壳体中旋转以将显影剂从搅拌构件传送到图像承载构件，并将调色剂附着到图像承载构件。 驱动装置旋转地驱动搅拌构件和显影单元主体中的至少一个。 检测装置检测驱动装置的扭矩。 当检测装置的检测结果具有低于阈值的值时，控制装置执行恢复处理，该恢复处理控制供应装置将载体和显影剂中的至少一个供应到壳体的内部。
