PURPOSE:To eliminate unevenness in development by forming a grooved wall surface close to the surface of a developer into the shape of a trigonal pyramid separating considerably from side edge parts of a film to prevent sucking phenomenon due to surface tension. CONSTITUTION:The developer storing section which serves also as a film conveying passage is composed of the 1st and 2nd blocks 1, 2 capable of being freely connected and separated, a tunnel type passage is formed in each of the blocks with grooves 3, 4, and a film F is conveyed in a developer 15. Then, a wall surface A separating considerably from side edges of the film at an upper part of the surface (l) of the developer on the film introduction side and a wall surface B approaching the film at a lower part of the surface (l) are formed. A funnel form part 30 of a trigonal pyramid is further formed having wall surfaces C, D separating from the film at an upper part of the surface (l) and approahing it at a lower part. Thus, the suction of the developer 15 is prevented to eliminate unevenness in development. |
