An image forming apparatus comprises an image bearing member on which an electrostatic image is formed, a development unit which develops the electrostatic image formed on the image bearing member using a developer and forms a developer image, a first transfer member which transfers the developer image on the image bearing member to an intermediate transfer member by a first transfer unit, a first recovery member which recovers the developer on the image bearing member, a second transfer member which transfers the developer image on the intermediate transfer member to a transfer material at a second transfer position, and a second recovery member which recovers the developer on the intermediate transfer member. The developer on the intermediate transfer member can be recovered by the second recovery means or by the first recovery member though the image bearing member, and the developer image can be continuously transferred to a plurality of transfer materials. The image forming apparatus further comprises a means which determines at the time of continuous transfer of the developer image to the plurality of the transfer materials, whether the developer on the intermediate transfer member is to be recovered by the second recovery member or by the first recovery member through the image bearing member, based on at least the time interval of sessions of developer image transfer to the transfer materials.

The present invention extends the lives of a photosensitive drum and a cleaning blade. A magnetic brush charging device is excellent in charging performance, and is effective to realize being ozoneless and the smoothing of the photosensitive drum, and the removal of a fused material therefrom. However, due to the smoothing action, a lubricant such as a toner decreases between the photosensitive drum and the edge portion of the cleaning blade, whereby the frictional force of the edge portion is increased and scraping-through by chattering of the toner becomes great. So, inorganic fine particles having the lubricating action are contained in at least the edge portion. Thereby, the hardness of the edge portion crises and the property thereof following the unevenness of the surface of the photosensitive drum is lowered, but the surface of the photosensitive drum is smooth and therefore, sufficient cleaning performance can be secured.
摘要:
A blade for regulating the amount of a release oil to be supplied is placed so as to abut on a fixing member or on a member for controlling the amount of the release oil to be supplied to the fixing member. The abutting surface of the blade is composed of a silicone rubber layer. Alternatively, the blade includes a plate-shaped elastic body and a silicone rubber layer formed on the tip of the elastic body. A fixing device including the blade and an image-forming apparatus including the fixing device are also disclosed.
