The invention relates to a process cartridge, a manufacturing method of the cartridge, and an image forming apparatus. The photoreceptor assembly (10) and the developing assembly (11) are connected in such a way that the side plates of the photoreceptor assembly (10) and the developing assembly (11) The parts (10a, 11a) are in surface contact, so that the pin insertion holes (40, 46) respectively formed on the side plate parts (10a, 11a) overlap, and the connecting pins are pressed into the above-mentioned pin insertion holes, and one side plate part The fitting protrusion (47) on (11a) is elastically fitted into the fitting hole (41) on the other side plate portion (10a). The photoreceptor assembly (10) and the developing assembly (11) are connected by an inexpensive structure without increasing the number of parts such as connecting plates, and the work can be performed simply without using jigs and the like.

The invention provides a screen for effectively utilizing space. A support leg (1B) comprises: a a support leg body (6) shaped substantially like a pillar, four leg sections (7) that support upright the support leg body (6) by abutting, at each one end, a placement surface, and a connection member (8) that is attached to the support leg body (6) and connects together the other end of each of the leg sections and the support leg body. The connection member (8) pivotally supports the other end of at least any of the leg sections (7) about a shaft substantially parallel to a vertical shaft. Through causing each leg sections (7) to rotate relative the connection member (8) using a shaft parallel with the vertical shaft as a center, the angle formed between each leg sections (7) using the support leg body (6) as the center is properly changed.

The invention discloses a pre-stressed anchor rod type steel internal support structure of a continuous arched slope protection pile and a construction method of the pre-stressed anchor rod type steel internal support structure Slope protection piles which are arrayed in a foundation pit are arranged transversely and anchorage forces of all the pre-stressed anchor rods distributed at intervals are transferred to the slope protection piles through anchor heads; the section steel internal support structure is formed by connecting an upper layer of I-steel and a lower layer of I-steel which are mutually parallel, connecting plates which are connected to the external faces of air-adjacent sides of the two I-steels, and anchor plates as well as end sealing plates which are connected to adjacent wing edges at slope-adjacent sides of the two I-steels; a vertical view of each section of the steel internal support structure is in an arch which is connected by three parts as follows: a middle part, a left part and a right part; the whole section steel internal support structure and the slope protection piles form a continuous arch; the middle part of each section of section steel support is flat as well as straight and connected with the anchor plates; the outer edge of the middle part is flushed with the air-adjacent sides of the slope protection piles; the left and right parts of each section of section steel support are located at the two sloping sides of the arch; and two external end supporting lugs of each section of section steel support are fixedly connected with left and right slope protection piles. According to the pre-stressed anchor rod type steel internal support structure and the construction method thereof disclosed by the invention, problems that the support of the external foundation pit projects out of the pile body, a foundation trench space is occupied as well as recycling and reutilization is unavailable are solved.
