An image forming apparatus is provided for forming an image on a recording material. The apparatus includes a cartridge supporting member on which a plurality of cartridges is detachably mountable. The cartridge supporting member is movable between an inside position inside a main assembly of the image forming apparatus and an outside position outside the main assembly. A plurality of preventing members are provided movably in the main assembly, with each preventing member being movable between a first position in which each preventing member prevents movement of the cartridge supporting member from the outside position to the inside position by contacting the cartridge supporting member, and a second position, retracted from the first position, in which each preventing member permits the movement of the cartridge supporting member.

Provided are: a paste composition which is capable of keeping a desired function for a backside electrode of a solar cell and strengthening the bond between an aluminum electrode layer and a p type silicon semiconductor substrate even if glass frit as a substance giving a bad effect on the environment is not incorporated into the composition or the content of glass frit as a substance giving a bad effect on the environment therein is decreased; and a solar cell element provided with an electrode formed by use of the composition. The paste composition is a paste composition for forming an aluminum electrode layer (8) over a p type silicon semiconductor substrate (1), comprising aluminum powder, an organic vehicle, and a metal alkoxide. The solar cell element provided with the aluminum electrode layer (8) formed by applying the paste composition having the above-mentioned characteristic to the p type silicon semiconductor substrate (1) and then firing the resultant.
摘要:
An image forming apparatus for forming an image on a recording material includes a cartridge accommodating a developer for developing an electrostatic latent image formed on a photosensitive member, a supporter detachably mounting the cartridge, and a preventor. The supporter moves between an inside position where the cartridge forms an image inside a main assembly of the apparatus and an outside position where the cartridge is mounted and demounted outside the main assembly. The preventor moves between a first position in which it prevents, when the cartridge is not mounted, movement of the supporter from the outside position to the inside position by contacting a portion thereof, and a second position, retracted from the first position, in which the it permits, when the cartridge is mounted, the movement of the supporter from the outside position to the inside position.
