Description
Claims (7)
- 현상제가 저장되어 있는 현상제 탱크와, 현상제 탱크 내에서 회전하는 교반부재와, 현상제 탱크의 일측에 마련되어 교반된 현상제를 현상기 측으로 이송하는 이송부재를 포함하는 현상제 공급장치를 구비한 화상형성장치에 있어서,상기 이송부재는 교반부재의 회전방향에 대향하여 이송부재로 유입된 현상제가 빠져나가는 것을 방지하기 위한 격벽을 구비하는 것을 특징으로 하는 화상형성장치.
- 제 1항에 있어서,상기 격벽은 이송부재의 이송방향을 따라 연속적으로 마련되는 것을 특징으로 하는 화상형성장치.
- 제 1항에 있어서,상기 격벽은 현상제 탱크의 일측으로부터 연장 마련되는 것을 특징으로 하는 화상형성장치.
- 제 3항에 있어서,상기 격벽은 바닥면으로부터 수직한 지점까지 마련되는 것을 특징으로 하는 화상형성장치.
- 제 1항 내지 제 4항 중 어느 한 항에 있어서,상기 격벽은 이송부재의 외주를 따라 형성되는 것을 특징으로 하는 화상형성장치.
- 제 1항에 있어서,상기 이송부재는 현상제 탱크의 일측에 일부가 인입 형성되는 것을 특징으로 하는 화상형성장치.
- 제 1항에 있어서,상기 현상제 탱크의 바닥면은 이송부재를 향해 상향 경사지는 것을 특징으로 하는 화상형성장치.
