A photographic light-sensitive material having a support having a thickness of from 160 to 225 &#x3bc;m is processed with an automatic developing apparatus, in which at least one of rollers of a developing part, a fixing part and a rinsing rack part of the automatic developing apparatus has a surface mainly containing a nonpolar polymer substance and having a center line surface roughness (Ra) of 20 &#x3bc;m or less. By using the automatic developing apparatus, dusts generated in the apparatus can be easily removed with a cleaning film.

A light-sensitive material package includes a light-shielding envelope containing a stack of sheet-form light-sensitive material, the light-shielding envelope having heat-seal parts on four edges. The light-sensitive material package further includes a cushioning member, which holds down all or a part of the heat-seal parts. The light-sensitive material package further includes a fitting-type box for storing the envelope, the fitting-type box being formed from an inner box and a lid. The stiffness of the heat-seal parts is at least 0.05 N&middot;cm.

A light-shielding packaging for a roll of continuous photosensitive web wound on a core having on its each end a light-shielding flange disc has at its leading end a heat-shrinkable light-shielding leader sheet having a thickness of 30 to 200 &mgr;m which shows a heat shrinkage ratio at 50&deg; C. of lower than 1% both in the longitudinal and width directions and a heat shrinkage ratio at 100&deg; C. in the range of 5% to 30% in the longitudinal direction and a heat shrinkage ratio at 100&deg; C. of less than the heat shrinkage ratio in the longitudinal direction by 1% or more in the width direction. The leader sheet has a length larger than the length of the outermost convolution of the roll and a width larger than the distance between the outer face of one flange disc and the outer face of another flange disc, and each side portion of the leader sheet is light-tightly attached by heat shrinkage to the outer face of the flange disc at least at a portion adjacent to the periphery of the flange disc.

A light-shielding packaging for a roll of continuous photosensitive web wound on a core having on its both ends a light-shielding flange disc has at its leading end a heat-shrinkable light-shielding leader sheet having a thickness of 30 to 200 &mgr;m which shows a heat shrinkage ratio of 5 to 30% in the longitudinal direction of the web at a temperature in the range of 60 to 140&deg; C. and a heat shrinkage ratio of less than 5% in its width direction at the same temperature. The leader sheet has a length larger than the length of the outermost convolution of the roll and a width larger than the distance between the outer face of one flange disc and the outer face of another flange disc, and each side portion of the leader sheet is light-tightly attached by heat shrinkage to the outer face of the flange disc at least at a portion adjacent to the periphery of the flange disc.

A rectangular parallelepipedic case includes four or more walls formed by bending a single plate. To produce the case, a double plate is used. The double plate is formed from plastic by extrusion, and first and second plate elements confronted with each other. Partition portions interconnect the first and second plate elements, and extend in the direction of the extrusion, to define plural hollow chambers between the first and second plate elements. The double plate is bent along bend lines substantially at a right angle. At least one of the bend lines is at least partially curved.

A container, for example a photographic paper magazine, includes a core about which photographic paper is wound in a form of a roll. A container body contains the roll with the core in a rotatable manner. An outlet slit is formed in the container body and adapted to drawing out the photographic paper. First and second end walls are disposed on the container body, and confronted with respective end faces of the roll. First and second core supports are supported respectively on the first and second end walls, rotatable coaxially, and fitted on respective axial ends of the core. The core supports support the core between the end walls in a rotatable manner. A lock pin is fixedly secured to the first end wall. A hook is disposed on the first core support, is engageable with the lock pin in a resilient manner, and inhibits relative rotation between the hook and the lock pin, to retain the first core support on the first end wall. An arm is displaceable between a free state and a deformed state, and biases the hook. The arm, when the first core support is initially mounted on the first end wall, is bent to the deformed state, to engage the hook with the lock pin. When the first core support is rotated by drawing the photographic paper, the hook is disengaged from the lock pin, to allow the arm to bend back to the free state. The arm moves the hook to a position deviated from the lock pin, and avoids interference with the lock pin.
