Abstract

본 발명은 이음매 없는 전사필름의 채용을 가능하게 하며 복사속도가 증진된 화상형성장치에 대해 개시한다. 이를 위한 본 발명은 전사드럼(40)의 좌우측 플랜지(42)(43)를 회전축(45)에 압입설치하고 그회전축(45)에 감광드럼(30)의 기어(32)와 맞물리는 기어(70)를 압입설치하여서, 감광드럼(30)의 회전력을 좌우측 플랜지(42)(43)에 동시에 전달할 수 있게 한다. 이에 따라서 좌우측 플랜지(42)(43)에 크로스 바아의 필요성을 제거하고 이음매 없는 전사필름(41)을 설치할 수 있게 하여 복사속도를 증진시킬 수 있게한다.The present invention discloses an image forming apparatus which enables the adoption of a seamless transfer film and whose copying speed is enhanced. To this end, the present invention press-installs the left and right flanges 42 and 43 of the transfer drum 40 to the rotary shaft 45 and meshes with the gear 32 of the photosensitive drum 30 to the rotary shaft 45. By press-fitting), the rotational force of the photosensitive drum 30 can be simultaneously transmitted to the left and right flanges 42 and 43. This eliminates the need for a cross bar on the left and right flanges 42 and 43 and enables the installation of the seamless transfer film 41 to increase the copy speed.
