摘要:
A blade member, mountable onto an electrophotographic image forming apparatus, such as copier, printer, facsimile, word processor, and the like, for removing residual matter from an electrophotographic photosensitive member, includes an elastic blade one side surface of which is flat in a longitudinal direction thereof and the other side surface of which has a vertical portion perpendicular to an end surface of the elastic blade, and an inclined portion inclined with respect to the vertical portion, the inclined portion having a larger thickness than the vertical portion, and a support member for supporting the elastic blade. A thickness (f) of a portion of the elastic blade, which is engaged by the support member at a side of the one side surface, is greater than a thickness (g) of a portion of the elastic blade which is engaged by the support member at a side of the other side surface.

A process cartridge mountable within an image forming apparatus, includes an image bearing member, process means acting on the image bearing member, a frame, and a first guide surface provided on the frame and adapted to guide a recording medium toward the image bearing member, and a second guide surface recessed more than the first guide surface and having width smaller than that of the first guide surface. With the above construction, it is possible to provide a process cartridge and an image forming apparatus within which such a process cartridge can be mounted, which can be made small-sized and light-weighted and which are easy to use.
摘要:
An electronic instrument comprises a printed circuit substrate on which electrical parts are actually mounted, a frame placed on the front side of the printed circuit substrate and having openings at least at positions corresponding to the electrical parts, a front sheet disposed at a position opposed to the printed circuit substrate with the frame interposed therebetween and provided with an adhesion margin on the peripheral portion thereof, a back sheet disposed on the back side of the printed circuit substrate and provided with an adhesion margin on the peripheral portion thereof, and an adhesive agent applied to the adhesion margins of the front sheet and the back sheet to cause the printed circuit substrate and the frame to be sandwiched between the front sheet and the back sheet.
