<p>PURPOSE:To feed a recording medium in a constant and reliable state from containing means and to improve reliability on feed and conveyance ability by a method wherein an electrification charge pattern or an unequal electric field pattern in a constantly specified shape is formed on a conveying means by means of an electrifying device, and an attraction force on the recording medium of the conveying means is uniformly generated. CONSTITUTION:A means to additionally move only a part in either a horizontal direction or a vertical direction is located to a conveying means 53. The conveying speed of a part is varied, an electrifying means 76 to form an unequal electric field pattern is located to the conveying means 53, and an unequal electric field pattern in a specified shape is formed on the conveying means 53. An electrifying charge pattern or an equal electric field pattern in a constantly specified shape is formed on the conveying means 53 by means of the electrifying means 76, and an attraction force exerted on a recording medium 77 on the conveying means 53 is uniformly generated. This constitution performs the feed of the recording medium 77 in a constant and reliable state from containing means 52 and 201-204 and improves reliability on feed and conveyance ability.</p> |
