渡り時間（クロスオーバータイム）も長くなる難点があ
る。However, in such a method, if the jetting speed of the processing liquid is increased in order to speed up the processing, the back surface of the photosensitive material comes into contact with the conveyance guide, which tends to cause scratches. This problem can be solved by increasing the distance between the conveyance guide and the back side of the photosensitive material, but this would require an increase in the size of the device.
The disadvantage is that the crossing time (crossover time) is also long.
従って、本発明の目的は、処理の迅速化のため、感光材

(The main body of the processing apparatus has a guide for a part of the leader, but not a guide for the negative part. Therefore, the negative part is pulled and conveyed by the leader while wandering in the processing liquid.) [Example] The following is a guide for the negative part. The invention will be described based on embodiments shown in the drawings.

求めればよい。The processing liquid spraying member 3 and the guide member 4 have nozzles 3a and 4a, respectively, which face the photosensitive material conveyance path 5 and are provided across the conveyance width of the photosensitive material. The processing liquid is sprayed from the nozzle 4a onto the back surface of the photosensitive material (on the side where the photosensitive layer is located). The spray angle from these nozzles to the surface of the photosensitive material is determined by (a) the conveyance direction of the photosensitive material (
It is preferable to spray the photosensitive material diagonally in the opposite direction (indicated by the dotted chain arrow), that is, so that the angle between the spraying direction and the transport path 5 is an acute angle. It may also be sprayed perpendicularly to the transport path, or (

ことができる。In the present invention, it is preferable to have an adjusting means for balancing the spraying pressure of the processing liquid from both sides of the photosensitive material in order to prevent the photosensitive material from coming into contact with the guide member and to ensure smooth conveyance. As the adjustment means, a metering pump is used as a pump for pumping the processing liquid to the respective spraying members on both the front and back sides of the photosensitive material, and the metering pump is divided into two systems, one for the front side and the other for the back side of the photosensitive material. It is possible to use a method of balancing the spray pressure by controlling the discharge flow rate of a metering pump, a method of providing a valve for each nozzle and adjusting it by the valve opening, and a combination of these methods.

消される。According to the present invention, in the process of processing a photosensitive material, the processing liquid is ejected onto the photosensitive layer surface of the photosensitive material and also onto the back side of the photosensitive material, so that the processing liquid is ejected onto the photosensitive layer surface in order to speed up the processing. Even when the jetting speed of the processing liquid is increased, the back surface of the photosensitive material does not come into contact with the guide member, and therefore, processing can be speeded up without causing scratches on the back surface of the photosensitive material. Furthermore, scratches on the back surface can be solved by increasing the distance between the back surface of the photosensitive material and the conveyance guide, but such a measure increases the size of the processing apparatus and increases the transit time. According to the present invention, the problem of scratches on the back surface of a photosensitive material can be solved without such drawbacks.
