    摘要: A developing apparatus includes a developing container for containing a developer; a developer carrying member to be rotated while carrying the developer thereon, the developer carrying member being provided in an opening portion of the developer container; and a sealing member which extends in a circumferential direction of the developer carrying member in the vicinity of an end of the developer carrying member and regulates movement of the developer toward the end of the developer carrying member by a magnetic force, the sealing member including an arcuate portion extended along a peripheral surface of the developer carrying member and a non-arcuate portion disposed at an end, in the circumferential direction, of the arcuate portion. An end surface of the arcuate portion of the sealing member on a side where the non-arcuate portion is not provided, is inclined such that a phantom plane including the end surface is closer to the arcuate portion than a center of arcuation of the arcuate portion.

    摘要: An electrophotographic image forming apparatus, capable of detachably mounting a process cartridge, for forming an image on a recording medium includes, a mounting portion for detachably mounting the process cartridge. The apparatus also includes a transporting member for transporting the recording medium, a controlling portion for controlling the operation of the electrophotographic image forming apparatus to execute the reading and/or the writing of the information to a storing member of the cartridge; and an exposing portion for exposing an electrophotographic photosensitive body of the cartridge to light. The electrophotographic image forming apparatus is configured to execute a charge elimination operation of the electrophotographic photosensitive body if the electrophotographic image forming apparatus determines that the process cartridge is in an unused state on the basis of the information from the storing member. As a result, an electrophotographic image forming apparatus and a process cartridge, both being capable of preventing the occurrence of image defects such as a black streak in an initial state of the process cartridge, are provided.

    摘要: A process includes an image bearing member unit; a developing unit; a shaft provided in either the image bearing member unit or the developing unit at an end portion of the process cartridge with respect to an image bearing member axial direction; and an opening, provided in the unit at the end portion, engaged with the shaft to permit movement of the developing unit relative to the image bearing member unit. The opening defines a first contact portion, when the process cartridge is mounted to a main assembly, contacting the shaft to permit movement of the developing unit, and defines a second contact portion, when the second contact portion contacts the shaft when the process cartridge is mounted to the main assembly and does not receive a driving force from the main assembly, contacting the developing unit so the shaft and the first contact portion are in contact.
