Abstract: A method of and an apparatus for supplying a record medium to an electrophotograph printer. The printer includes a photosensitive means on which are formed electrostatic latent images concerning with images to be printed on the basis of images data. The latent images are then converted by applying toner to the latent images to sensible images which are then transferred to the record medium at a transfer position where the sensible images are in opposition to a printable zone of the record medium to form printed images. A time from starting motion of the photosensitive means to a moment when the sensible images have arrived at the transfer position is predetermined and the record medium is supplied into the printer so that a leading end of the printable zone of the record medium arrives at the transfer position when the sensible images have arrived at the transfer position.
