As the alkali  agent being used  for  adjusting pH, an  ordinary water-soluble  inorganic alkali  metal salt such as  sodium hydroxide,  potassium hydroxide,  sodium carbonate,  potassium carbonate,  potassium tertiary  phosphate, etc., can  be used.  As the  preservative, sulfites  can be used. As the  sulfites,  there are sodium  sulfite, potassium  sulfite, lithium sulfite,  ammonium sulfite,  sodium bisulfite,  potassium bisulfite,  potassium metabisulfite,  etc. The addition  amount of the  preservative  is  preferably not more  than 0.5 mol per liter  of  the developer.  It  is preferable that  the developer further  contains a  preservative and alkali  in addition to the  foregoing necessary  components.  For the developer  of this invention,  an  aminophenol  derivative developing  agent is used. As  the  aminophenol  derivative developing  agent, there are  4-aminophenol,  4-amino- 3-methylphenol,  4-(N-methyl)aminophenol,  2,4- diaminophenol,  N-(4-hydroxyphenyl)glycine,  N-(2’-hy› droxyethyl)- 2-arninophenol,2-hydroxymethyl-4-aminophc› nol,  2-hydroxymethyl-4-(N-methyl)arninophenol,  etc., and  the  hydrochlorides  and sulfates of these  compounds,  and  N-methyl- 4-aminophenol  sulfate (Metal) is  particularly  preferred. The addition  amount of the aminophenol  deriva› tive developing agent  to the developer  is from 0.5 g to 10  g  per liter of the developer.  The reductone compounds  for use in this invention  can be  used as the forms  of the alkali metal  salts such as lithium  salts, sodium salts,  potassium salts, etc.  It is preferred that  the reductone compound  is used in an amount  of from l to  100 g per liter of  the developer.  Examples of other  reductone compounds:  t,Hlrn  Examples of the endiol  type reductone compound:  t,0IJ!JI)  Then, specific examples  of the  particularly preferred  reductone compounds  for use in this invention  are shown  below.  The particularly preferred  reductone compounds  for use  in this invention  are the compounds  shown by formula  (I)  described above.  Examples of these  compounds are described  in U.S. Pat.  No. 2,688,549 and  JP-A-62-237443.  The synthesis methods  of these reductone  compounds are well  known and they are  described in-detail,  e.g., in Yuuji Nomura  and Hirohisa  Oomura,  Reductone  no Kagaku  (Chemistry  of  Reductone),  published by Uchida  Rookakuho Shinsha  K.K.,  1969.  Then, the reductone  compounds which  are used for the  developer of the  present invention  are generally lmown  as  endiol type compounds,  enaminol type compounds,  endi› amine type compounds,  thiol-enol type compounds,  and  enarninethiol  type compounds.  For adding the compounds  shown by formulae  (C-I),  (C-11), (C-III), and  (C-IV) for use in  this invention to  the  developer, they may  be added thereto as  a solution thereof  in water or an organic  solvent miscible with  water, such as  methanol, ethanol,  triethylene glycol,  diethylene glycol,  etc.  Furthermore, these  compounds may  be directly added  to the  developer.  The addition amount  of each of the  compounds shown  by  formulae (C-1), (C-11),  (C-III), (C-IV) for  use in this inven› tion to the developer  is from 0.01 g to 100  g, and preferably  from 0.1 g to 50 g  per liter of the developer.  The foregoing  compounds may  be used singly or  as a  combination  of them.  trial chemicals.
