摘要： A developing device is provided with a toner container rotatable to a toner replenishing position. The toner container has a toner outlet in a wall of the container. This outlet includes an edge portion that is downstream in the direction of the rotation of the container that is jutted towards the center of toner container rotation which is inside the toner container. This inwardly jutted edge portion of the toner outlet provides a toner outlet profile having an edge that is lower than the other edge of the toner outlet in the direction of toner container rotation so that the lower edge does not engage into contact with a toner inlet on a wall of a developing chamber of a developing device until after the toner outlet is in a position overlapping at least most of the toner inlet. The toner container can further be provided with an internal plate mounted to pivot from a position where the plate extends along an inner surface of the toner container which is spaced from but generally faces the toner outlet and a position where the swinging end of the plate pivots closer to the toner outlet without blocking it so as to help expel any toner that may have become compacted near the toner outlet. A drive device is provided to rotate the container into a position in which it provides toner to the developing chamber of the development unit from the toner outlet of the toner container via the overlapped toner inlet with the plate swinging to its second position to insure that toner that may be massed near the outlet portion can be expelled.

摘要： In an image forming apparatus, a rotary developing device has a developing unit in which a plurality of developing chambers are arranged around an axis of rotation. The developing unit is rotated about the axis to bring one of the chambers to a developing position where an image carrier is located. In each of the chambers, part of a developer removed by a doctor blade is received by a guide and then released from the guide into the chamber. This part of the developer is agitated in the vertical direction and conveyed together with the developer existing in the chamber by the rotation of the device. As a result, the developer is agitated, conveyed and charged in a desirable manner.

摘要： A method of removing a film from a photoconductive element of a color copier or similar image forming apparatus. At a suitable time when an image forming mode operation for forming a toner image on the photoconductive element is not under way, an amount of cleaning agent great enough to scrape a film off the photoconductive element is transported to a region between the photoconductive element and a cleaning sleeve. Subsequently, the amount of cleaning agent to be transported to such a region is reduced. This sequence of steps is repeated a plurality of times.

摘要： An image forming apparatus whereby it is possible to prevent unevenness in developing density caused by misalignment between the central axes of a driven side rotational coupling section for rotating a developer carrier and a drive side rotational coupling section for transmitting rotational drive force to the driven side rotational coupling section. The driven side rotational coupling section is fixed and the position thereof can be corrected slightly, by engaging the driven side rotational coupling section with a drive side rotational coupling section. A transmission gear is provided which meshes with the driven side rotational coupling section and transmits rotational drive force used to move the surface of the developer carrier. By means of an axle provided on at least one end of the transmission gear engaging with a positioning member on the main body of the image forming apparatus, the developer carrier is positioned in the main body of the image forming apparatus.

摘要： In an image forming apparatus, a developing device has a toner container having a toner outlet, and a receptacle having a mount portion for removably mounting the container. The insertion space of the mount portion and the toner outlet are each tapered such that the width in the up-and-down direction sequentially decreases toward the deepest end. In a developing device of the type causing the container to be rotated to bring the toner outlet into alignment with a toner inlet formed in the receptacle, the edge portion of the toner outlet is tapered to reduce a load during rotation and to ensure close contact at the end of the mounting of the container.
