In a laser beam printer, automatic optical quantity (APC) control is performed based on an optical quantity detection output to generate a laser beam having a predetermined quantity of light. In each scanning cycle, APC is effected by utilizing a period (unblanking period) in which the laser device is forcibly actuated to generate a horizontal synchronization signal. The unblanking period may be changed according to the print paper size or image formation/non-image-formation periods. Also, light quantity control may be effected through a plurality of scanning cycles before image formation and may be effected by utilizing the unblanking period during the period corresponding to the intervals of print sheets. Techniques also provided to prevent a transfer unit from being contaminated by toner images formed as a byproduct of APC.

Disclosed is an improved floating electric connector comprising male and female counterparts each having a housing and a metal shell. The male housing has a plurality of electric signal transmission male terminals fitted therein whereas the female terminals fitted therein. Each metal shell has a blade contact integrally connected thereto for inserting an associated female terminal. The metal shell-and-blade contact integral structure permits the simultaneous grounding and destaticizing.
