Title: Image forming device
Inventor: SAKAKIBARA KENJI
IPC: G03D13/00
Filed: 1989-10-26
Abstract: PURPOSE:To prevent normal paper from jamming even when heat-fixed in OHP mode by making the conveying speed of a recording form which uses an OHP sheet as its base slower than the conveying speed when normal paper is used as the base. CONSTITUTION:A relatively fast speed for normal paper (normal paper speed) or a relative slow OHP form speed (OHP form speed) is selectable previously as the speed of heat fixation as to a heat-fixation feed motor 54. At this time, the heating temperature of heat fixation is set to temperature at which an excellent copy image is obtained on the recording form which uses the normal paper as its base when pressure development is performed at the normal paper speed. Then an operator operates an operation part 52 to set 'OHP mode' or 'normal paper mode' and when a CPU 51 judges 'OHP mode', the CPU performs control for slowing down the speed of the heat-fixation feed motor 54 as the OHP form speed. Consequently, even if the normal paper is used by mistake, there is no deformation and no jam is therefore caused.
