Claims (6)
- 대전, 노광, 현상의 공정을 복수회 반복하여 감광체상에 색이 상이한 복수의 토우너상을 형성하는 컬러전자사진방법에 있어서, 앞공정에서 형성한 제1의 토우너상에 인접해서 제2의 토우너상을 형성할때, 상기 제1의 토우너상과의 경계부에 비화선영역을 형성하여 상노광하는 것을 특징으로 하는 컬러전자사진방법.
- 제1항에 있어서, 비화선영역의 폭이 0.02mm∼0.2mm의 범위인 컬러전자사진방법.
- 제1항에 있어서, 제전수단이 광조사인 컬러전자사진방법.
- 제1항에 있어서, 현상이 네거티브·포지티브 반전 현상인 컬러전자사진방법.
- 대전, 노광, 현상의 공정을 복수회 반복하여 감광체상에 색이 상이한 복수의 토우너상을 형성하는 컬러전자사진장치에 있어서, 앞공정에서 형성한 제1의 토우너상에 인접하여 제2의 토우너상을 형성할때, 상기 제1의 토우너상과의 경계부에 비화선영역을 형성하여 상노광하는 수단을 착설한 것을 특징으로 하는 컬러전자사진장치.
