Estimating the term…
A remanufacturing method of a developing device including a developer accommodating portion partitioned by a partitioning portion, a first opening provided in the partitioning portion and a seal member welded on the partitioning portion surrounding the first opening, wherein the first opening is opened by removing the seal member to supply a developer to the outside is provided. The method includes hermetically sealing, before or after re-filling the developer in the developer accommodating portion for reuse, the first opening by boning, on the partitioning portion, a plate-like member, which is provided with a second opening corresponding to the first opening and on which a reseal member for sealing the second opening is detachably bonded, at a region outside a welding trace, a region inside the trace, or a region ranging from an inside to an outside of the trace so as to cover the welding trace.
A remanufacturing method of a developing device, comprising a developer accommodating portion partitioned by a partitioning portion, a first opening provided in the partitioning portion and a seal member, welded on the partitioning portion which surrounds the first opening, for sealing the first opening, wherein the first opening is opened for use by removing the seal member from the partitioning portion to supply a developer to an outside of the developer accommodating portion through the first opening, said method comprising:
A developing device for use with an electrophotographic image forming apparatus, comprising:
A remanufacturing method of a process cartridge, comprising an electrophotographic photosensitive member, a developing chamber provided with a developer carrying member for developing an electrostatic latent image formed on the electrophotographic photosensitive member with a developer, a developer accommodating portion partitioned from the developing chamber by a partitioning portion, a first opening provided in the partitioning portion and a seal member, welded on the partitioning portion which surrounds the first opening, for sealing the first opening, wherein the first opening is opened for use by removing the seal member from the partitioning portion to supply the developer from the developer accommodating portion to the developing chamber, said method comprising:
A process cartridge detachably mountable to an electrophotographic image forming apparatus, comprising:
