Abstract
A processing apparatus for a light-sensitive material includes a plurality of processing tanks for processing light-sensitive material; a kit including a container for accommodating a number of solid processing agents used for each processing tank; and solid processing agent replenishing device for replenishing the solid processing agents accommodated in the container into each processing tank. The apparatus further includes a memory for storing an amount of each solid processing agent used for processing a predetermined amount of light-sensitive material; a residual amount detector for detecting a residual amount of each solid processing agent and outputting a used up solid-processing-agent signal when the residual amount of each solid processing agent becomes zero; and a replacement requesting device for requesting the replacement of all solid processing agents in accordance with the used up solid-processing-agent signal of the solid processing agent.
