IMAGE FORMING APPARATUS AND IMAGE FORMING METHOD

摘要

An image forming apparatus includes a fixing member to fix toner to a recording medium, a heating control part to heat the fixing member to a specified temperature, a measuring part to measure a temperature of the fixing member, and a calculation part to calculate an arrival time required until the temperature of the fixing member reaches a target temperature based on a difference between the target temperature at a warming-up end time of the fixing member and the temperature measured by the measuring part. If the arrival time is shorter than a rise time required to warm up the image forming apparatus, the heating control part starts to heat the fixing member after a specified time passes from a time when warming-up of the image forming apparatus is started.

主权项

1. An image forming apparatus for forming an image on a recording medium, comprising:
a fixing member to fix toner to the recording medium; a heating control part to heat the fixing member to a specified temperature; a measuring part to measure a temperature of the fixing member; and a calculation part to calculate an arrival time required until the temperature of the fixing member reaches a target temperature based on a difference between the target temperature at a warming-up end time of the fixing member and the temperature measured by the measuring part, wherein in response to a determination by the calculation part that the arrival time is shorter than a warm-up time required to warm up the image forming apparatus except for the fixing device, the heating control part starts to heat the fixing member after a specified time passes from a time when warming-up of the image forming apparatus is started.
