Abstract: A sheet feed device comprises: a retaining section retaining a sheet; a drive section raising the retaining section; a conveyance section conveying a sheet on the raised retaining section; a sheet detection section detecting an end of the conveyed sheet; and a control section. At the time that a sheet feed instruction is received, when a sheet is detected by the sheet detection section, the control section causes the conveyance section to feed the sheet further. When a sheet is not detected, the control section causes the drive section to raise the retaining section and then causes the conveyance section to start conveyance of a sheet.

Abstract: A thermal fixing device for fixing toner images onto recording sheets includes a heat member, a pressing member, a temperature sensor, a clock, and a control unit. The control unit performs a toner fixing control and a high-temperature heat-up control. During the toner fixing control, the control unit controls the heat member to heat up to a fixing temperature required to melt toner on a recording sheet disposed between the heat member and the pressing member. During the high-temperature heat-up control, the control unit controls the heat member to heat up to a high-temperature fixing temperature that is higher than the fixing temperature. The control unit sets length of the high-temperature heat-up control in accordance with length of the start-up time measured by the clock.
