Title:
IMAGE FORMING APPARATUS
Document Type and Number:
Japanese Patent JP2019086688
Kind Code:
A
Abstract:
To appropriately perform initialization operation irrespective of an order of the initialization operation of a developing unit and attachment to a storage container.SOLUTION: Whether or not this time power supply turning on is first time (initial time) power supply turning on after shipping an image forming apparatus is determined. When it is determined that this time power supply turning on is the first time power supply turning on after shipping the image forming apparatus, since initialization operation is necessary, whether or not a toner container is attached to a toner supply part is determined. When the toner container is attached, warning to prompt removal of the attached toner container is performed, and an inflow flag is set ON to return a process to a step S202. When the toner container is not attached to the toner supply part, a developing motor is rotated to perform idle rotation of a developing unit for predetermined time. Next, whether or not the inflow flag is ON (whether or not a toner flows into the developing unit) is determined, a control voltage to be applied to an inductance sensor for setting a reference value Vref being a target output is made different depending on whether the inflow flag is ON or OFF.SELECTED DRAWING: Figure 7
