Fixing device that reduces friction against sheet and image forming apparatus including the same

A fixing device for applying pressure to and heating a sheet on which a toner image is formed to weld toner onto the sheet so as to fix the toner image, the fixing device comprising:

• a heating member internally including a heating element;
• a pressure member including an elastic layer located to be pressed against the heating member to ensure a fixing nip area between the heating member and the pressure member;
• and
• a conveyance guide located upstream with respect to the fixing nip area in a conveying path of a sheet on which the toner image is formed, the conveyance guide assisting the sheet to run;
• wherein
• the conveyance guide includes
• a first guiding portion that guides a head of the sheet to a distal end position close to the heating member, the first guiding portion including an inclined surface that continues from an upstream side with respect to the distal end position of the conveying path of the sheet, to the distal end position, and
• a second guiding portion that guides a tail of the sheet from the distal end position to an intermediate position between the heating member and the pressure member, the second guiding portion including a stairs that continues from the distal end position to the intermediate position.
