发明名称 IMAGE FORMING APPARATUS
摘要 To provide an image forming apparatus that can highly accurately position and convey, even if an inter-sheet distance of sheets to be conveyed is reduced, the sheets from registration rollers to a transfer position when a toner image on an image bearing member moving at process speed is transferred onto the sheet in the transfer position. A sheet fed from a paper feeding cassette by a pulse-motor driven paper feeding roller is conveyed to pulse-motor driven registration rollers by pulse-motor driven conveying rollers. When the sheet is conveyed to the transfer position according to restart of the registration rollers, the sheet is conveyed by the registration rollers at sheet conveying speed different from the process speed before the leading end of the sheet reaches the transfer position and is conveyed at the process speed after that.
