PROBLEM TO BE SOLVED: To adjust sheet carrier speed on a resist roller so that favourable picture image formation is carried out without complicating constitution. SOLUTION: The number of rotation of a paper feeding motor 40 which is a rotational driving source of a resist roller 23, that is, a setting value of exciting time for a stepping motor is changed and sheet carrier speed of the resist roller 23 is adjusted to enter a proper range by carrying out setting value changing input from an outside operating part 36 to a roller driving control part 33 in the case when the sheet carrier speed is not proper speed due to dispersion of the resist roller 23, etc. |
