发明名称 IMAGE FORMING DEVICE
摘要 <p>PURPOSE:To prevent a transfer shift by providing a pair of pre-transfer carrying rollers in the vicinity of the image carrying body of a sheet guide means. CONSTITUTION:At least a pair of pre-transfer carrying rollers 21, 22 is provided in the vicinity of the image carrying body 15 of a sheet guide means 9. A sheet S is carried by a pair of resist rollers 10, sandwiched by the pre-transfer roller 22 and the pre-transfer auxiliary roller 21 and carried to a transfer position, and a developed image is transferred by a transfer electrifier 12. Subsequently, when the rear end of the sheet S is separated from the resist rollers 10, the rear end of the sheet S springs up to a broken line position D from a full line position C, but since the front of the sheet S is sandwiched by the pre-transfer roller 22 and the pre-transfer auxiliary roller 21, a shock when the rear end of the sheet S springs up is absorbed by the rollers 22, 21, and it is not transferred to the transfer position of the sheet S. In such a way, a transfer shift is prevented.</p>
